Add a capability for userspace to mirror SEV encryption context from
one vm to another. On our side, this is intended to support a
Migration Helper vCPU, but it can also be used generically to support
other in-guest workloads scheduled by the host. The intention is for
the primary guest and the mirror to have nearly identical memslots.
The primary benefits of this are that:
1) The VMs do not share KVM contexts (think APIC/MSRs/etc), so they
can't accidentally clobber each other.
2) The VMs can have different memory-views, which is necessary for post-copy
migration (the migration vCPUs on the target need to read and write to
pages, when the primary guest would VMEXIT).
This does not change the threat model for AMD SEV. Any memory involved
is still owned by the primary guest and its initial state is still
attested to through the normal SEV_LAUNCH_* flows. If userspace wanted
to circumvent SEV, they could achieve the same effect by simply attaching
a vCPU to the primary VM.
This patch deliberately leaves userspace in charge of the memslots for the
mirror, as it already has the power to mess with them in the primary guest.
This patch does not support SEV-ES (much less SNP), as it does not
handle handing off attested VMSAs to the mirror.
For additional context, we need a Migration Helper because SEV PSP
migration is far too slow for our live migration on its own. Using
an in-guest migrator lets us speed this up significantly.

This helps validating DTS files.
Changes that require mentioning:
1. reg-names
"mspi_regs" and "bspi_regs" were renamed to "mspi" and "bspi" as that
is what's used in DTS files and in Linux driver
2. interrupt-names
Names were reordered. "mspi_done" has to go first as it's always
required.
3. spi-rx-bus-width
Property description was dropped as it's part of the
spi-controller.yaml
4. Examples:
* drop partitions as they are well documented elsewhere
* regs and interrupts were formatted and reordered to match yaml
* <0x1c> was replaced with <&gic>
* "m25p80" node name became "flash"
* dropped invalid "m25p,fast-read" property
* dropped undocumented and Linux-unused "clock-names"
This rewritten binding validates cleanly using the "dt_binding_check".
Some Linux stored DTS files will require reordering regs and interrupts
to make dtbs_check happy.

Commit 60268b0e8258 ("hwmon: (amd_energy) modify the visibility of
the counters") restricted visibility of AMD energy counters to work
around a side-channel attack using energy data to determine which
instructions are executed. The attack is described in 'PLATYPUS:
Software-based Power Side-Channel Attacks on x86'. It relies on quick
and accurate energy readings.
This change made the counters provided by the amd_energy driver
effectively unusable for non-provileged users. However, unprivileged
read access is the whole point of hardware monitoring attributes.
An attempt to remedy the situation by limiting and randomizing access
to chip registers was rejected by AMD. Since the driver is for all
practical purposes unusable, remove it.

Hardware monitoring sysfs attributes are used and displayed by unrestricted
userspace applications. Standard attributes therefore have to be world
readable, since otherwise those userspace applications would either have
to run as super-user or display an error. None of those makes sense.

Add pmbus driver support for Maxim MAX15301 InTune Automatically
Compensated Digital PoL Controller with Driver and PMBus Telemetry
Even though the specification does not specifically mention it,
extensive empirical testing has revealed that auto-detection of
limit-registers will fail in a random fashion unless the delay
parameter is set to above about 80us. The default delay is set
to 100us to include some safety margin.

This patch adds support for these devices:
- YH-5151E - the PDU
- YM-2151E - the PSU
The device datasheet says that the devices support PMBus 1.2, but in my
testing, a lot of the commands aren't supported and if they are, they
sometimes behave strangely or inconsistently. For example, writes to the
PAGE command requires using PEC, otherwise the write won't work and the
page won't switch, even though, the standard says that PEC is optional.
On the other hand, writes to SMBALERT don't require PEC. Because of
this, the driver is mostly reverse engineered with the help of a tool
called pmbus_peek written by David Brownell (and later adopted by my
colleague Jan Kundrát).
The device also has some sort of a timing issue when switching pages,
which is explained further in the code.
Because of this, the driver support is limited. It exposes only the
values that have been tested to work correctly.

Add support for TI TPS53676 controller to the tps53679 pmbus driver
The driver uses the USER_DATA_03 register to figure out how many phases
are enabled and to which channel they are assigned, and sets the number
of pages and phases accordingly.

These are "all-in-one" CPU liquid coolers that can be monitored and
controlled through a proprietary USB HID protocol.
While the models have differently sized radiators and come with varying
numbers of fans, they are all indistinguishable at the software level.
The driver exposes fan/pump speeds and coolant temperature through the
standard hwmon sysfs interface.
Fan and pump control, while supported by the devices, are not currently
exposed. The firmware accepts up to 61 trip points per channel
(fan/pump), but the same set of trip temperatures has to be maintained
for both; with pwmX_auto_point_Y_temp attributes, users would need to
maintain this invariant themselves.
Instead, fan and pump control, as well as LED control (which the device
also supports for 9 addressable RGB LEDs on the CPU water block) are
left for existing and already mature user-space tools, which can still
be used alongside the driver, thanks to hidraw. A link to one, which I
also maintain, is provided in the documentation.
The implementation is based on USB traffic analysis. It has been
runtime tested on x86_64, both as a built-in driver and as a module.

Adds support for reading the critical values of the temperature sensors
and the rail sensors (voltage and current) once and caches them. Updates
the naming of the constants following a more clear scheme. Also updates
the documentation and fixes some typos. Updates is_visible and ops_read
functions to be more readable.
The new sensors output of a Corsair HX850i will look like this:
corsairpsu-hid-3-1
