In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.
While at it, also remove a redundant call to of_address_to_resource(),
as this was getting the address of the same resource index 0: we can
as well get the iostart from the 'regs' pointer.

Changes from v1:
* replace some accidental spaces with tabs
In commit f145d411a67e ("crypto: rsa - implement Chinese Remainder Theorem
for faster private key operations") we have started to use the additional
primes and coefficients for RSA private key operations. However, these
additional parameters are not present (defined as 0 integers) in the RSA
test vectors.
Some parameters were borrowed from OpenSSL, so I was able to find the
source. I could not find the public source for 1 vector though, so had to
recover the parameters by implementing Appendix C from [1].

qat_4xxx devices can be configured to allow either crypto or compression
operations. At the moment, devices are configured statically according to
the following rule:
- odd numbered devices assigned to compression services
- even numbered devices assigned to crypto services
Expose the sysfs attribute /sys/bus/pci/devices/<BDF>/qat/cfg_services
to allow to detect the configuration of a device and to change it.
The `cfg_service` attribute is only exposed for qat_4xxx devices and it

"dc" for compression services.

The function adf_cfg_add_key_value_param() allows to insert duplicates
entries in the key value store of the driver.
Change the behaviour of that function to the following policy:
- if the key doesn't exist, add it;
- if the key already exists with a different value, then delete it and
replace it with a new one containing the new value;
- if the key exists with the same value, then return without doing
anything.
The behaviour of this function has been changed in order to easily
update key-values in the driver database. In particular this is required
to update the value of the ServiceEnables key used to change the service
loaded on a device.

Expose the device state through an attribute in sysfs and allow to
change it. This is to stop and shutdown a QAT device in order to change
its configuration.
The state attribute has been added to a newly created `qat` attribute
group which will contain all _QAT specific_ attributes.
The logic that implements the sysfs entries is part of a new file,
adf_sysfs.c. This exposes an entry point to allow the driver to create
attributes.
The function that creates the sysfs attributes is called from the probe
function of the driver and not in the state machine init function to
allow the change of states even if the device is in the down state.
In order to restore the device configuration between a transition from
down to up, the function that configures the devices has been abstracted
into the HW data structure.
The `state` attribute is only exposed for qat_4xxx devices.

The SiFive errata code contains code checking applicable erratas
vs. actually applied erratas to suggest missing erratas to the
user when their Kconfig options are not enabled.
In the main kernel image one can be quite sure that all available
erratas appear at least once, so that check will succeed.
On the other hand modules can very well not use any errata-relevant
code, so the newly added module-alternative support may also patch
the module code, but not touch SiFive-specific erratas at all.
So to restore the original behaviour don't warn when patching
modules. This will keep the warning if necessary for the main kernel
image but prevent spurious warnings for modules.
Of course having such a vendor-specific warning may not be needed at
all, as CONFIG_ERRATA_SIFIVE is selected by CONFIG_SOC_SIFIVE and the
individual erratas are default-y so disabling them requires
deliberate action anyway. But for now just restore the old behaviour.

dev_pm_opp_set_opp() can be called for any device, it may or may not
have a frequency value associated with it.
If a frequency value isn't available, we pass 0 to _set_opp(). Make it
optional instead by making _set_opp() accept a pointer instead, as the
frequency value is anyway available in the OPP. This makes
dev_pm_opp_set_opp() and _set_opp() completely independent of any
special key value.

Reuse _opp_compare_key() in _opp_add_static_v2() instead of just
comparing frequency while finding suspend frequency. Also add a comment
over _opp_compare_key() explaining its return values.

commit 32715be4fe95 ("opp: Fix adding OPP entries in a wrong order if
rate is unavailable") removed the only user of this field, get rid of
rest of it now.

The OPP table is called "opp_table" at most of the places and "table" at
few. Make all of them follow the same naming convention, "opp_table".

There are three type of helpers, to find exact, ceil, and floor values,
replicated for multiple key types, freq, level, bw. And all of these
helpers share a lot of boilerplate code.
Add generic key finding helpers to reduce code redundancy.
Also update the freq finder helpers to use the new infrastructure.

This was added few years back, but the code that was supposed to use it
never got merged. Remove the unused helper.

The only user of the custom helper is migrated to use
dev_pm_opp_set_config_regulators() interface. Remove the now unused
custom OPP helper support.
This cleans up _set_opp() and leaves a single code path to be used by
all users.

The OPP core now provides dev_pm_opp_set_config_regulators() interface,
which needs the platforms to just set the OPP voltages instead of both
clk and voltage. The clock is set by the OPP core instead and hence
reduces code redundancy.
Migrate the only user of the custom set_opp() to
dev_pm_opp_set_config_regulators().
