ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

Add a driver which allows powering off the system via an Intel PIIX4
southbridge, by entering the PIIX4 SOff state. This is useful on the
MIPS Malta development board, where it will power down the FPGA based
board until its ON/NMI button is pressed, or the QEMU implementation of
the MIPS Malta board where it will cause QEMU to exit.

This driver parses the reboot commands like "reboot bootloader"
and "reboot recovery" to get a boot mode described in the
device tree , then call the write interfae to store the boot
mode in some place like special register or sram, which can
be read by the bootloader after system reboot, then the bootloader
can take different action according to the mode stored.
This is commonly used on Android based devices, in order to
reboot the device into fastboot or recovery mode.

This patch introduces a new compatible string: "atmel,sama5d3-rstc" and
new reset function for sama5d3 and later chips.
As in sama5d3 or later chips, we don't have to shutdown the DDR
controller before reset. Shutdown the DDR controller before reset is a
workaround to avoid DDR signal driving the bus, but since sama5d3 and
later chips there is no such a conflict.
So in this patch:
1. the sama5d3 reset function only need to write the rstc register
and return.
2. we can remove the code related with sama5d3 DDR controller as
we don't use it at all.

Pull module_platform_driver replacement from Paul Gortmaker:
"Replace module_platform_driver with builtin_platform driver in non
modules.
We see an increasing number of non-modular drivers using
modular_driver() type register functions. There are several downsides
to letting this continue unchecked:
- The code can appear modular to a reader of the code, and they won't
know if the code really is modular without checking the Makefile
and Kconfig to see if compilation is governed by a bool or
tristate.
- Coders of drivers may be tempted to code up an __exit function that
is never used, just in order to satisfy the required three args of
the modular registration function.
- Non-modular code ends up including the <module.h> which increases
CPP overhead that they don't need.
- It hinders us from performing better separation of the module init
code and the generic init code.
So here we introduce similar macros for builtin drivers. Then we
convert builtin drivers (controlled by a bool Kconfig) by making the
following type of mapping:
module_platform_driver() ---> builtin_platform_driver()
module_platform_driver_probe() ---> builtin_platform_driver_probe().
The set of drivers that are converted here are just the ones that
showed up as relying on an implicit include of <module.h> during a
pending header cleanup. So we convert them here vs adding an include
of <module.h> to non-modular code to avoid compile fails. Additonal
conversions can be done asynchronously at any time.
Once again, an unused module_exit function that is removed here
appears in the diffstat as an outlier wrt all the other changes"

This file depends on Kconfig options all of which are a bool, so
we use the appropriate registration function, which avoids us
relying on an implicit inclusion of <module.h> which we are
doing currently.
While this currently works, we really don't want to be including
the module.h header in non-modular code, which we'd be forced
to do, pending some upcoming code relocation from init.h into
module.h. So we fix it now by using the non-modular equivalent.

gpio-restart uses a priority of 128 and currently most soc-level restart
mechanisms use the same - with some exceptions even using 192.
But while the soc-level restarts are provided by the soc itself,
gpio-restarts will most of the time be board-specfic and be used
when some special board condition makes the soc-level restart
only a second choice.
The problem at hand manifested itself on the rk3288-veyron devices.
While the soc-level restart can sucessfully restart all other rockchip
boards I have, the veyron devices use an external restart mechanism that
seems to not only reset the soc but also some external needed components.
With both restart handlers having priority 128 in my tests the soc-specific
variant took precedent in all cases. While it could restart the soc
sucessfully in all cases, firmware then got an issue when talking to an
external component, resulting in the device being put into recovery mode.
So, give the board-specific restart handler a slight push and move it
to priority 129 to make it more important than the generic soc-specific
restart-handler.

The Broadcom STB reboot driver depends on MFD_SYSCON, it uses
syscon_regmap_lookup_by_phandle() which will not lookup syscon phandles
if MFD_SYSCON is disabled, and instead will return -ENOSYS since it is
turned into an inline stub.

The return value of hrtimer_start() tells whether the timer was
inactive or active already when hrtimer_start() was called.
The code emits a bogus warning if the timer was active already
claiming that the timer could not be started.
Remove it.

In case of error, the function devm_ioremap() returns NULL
not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Remove it along with the bogus comment in the else path.
