PMU is something like a SoC wide service, so add a helper function to get
PMU regmap. This will be used by other Exynos device drivers. This way it
can be avoided to model this dependency in device tree (as phandles to PMU
node) for almost every device in the SoC.

The function wkup_m3_rproc_boot_thread waits for asynchronous
firmware loading to parse the resource table before calling
rproc_boot(). However, as the resource table parsing has been
moved to rproc_boot(), there's no need to wait for the
asynchronous firmware loading completion. So, drop this.

The General Register Files are an area of registers containing a lot
of single-bit settings for numerous components as well full components
like usbphy control. Therefore all used components are accessed
via the syscon provided by the grf nodes or from the sub-devices
created through the simple-mfd created from the grf node.
Some settings are not used by anything but will need to be set up
according to expectations on the kernel side.
Best example is the force_jtag setting, which defaults to on and
results in the soc switching the pin-outputs between jtag and sdmmc
automatically depending on the card-detect status. This conflicts
heavily with how the dw_mmc driver expects to do its work and also
with the clock-controller, which has most likely deactivated the
jtag clock due to it being unused.
So far the handling of this setting was living in the mach-rockchip
code for the arm32-based rk3288 but that of course doesn't work
for arm64 socs and would also look ugly for further arm32 socs.
Also always disabling this setting is quite specific to linux and
its subsystems, other operating systems might prefer other settings,
so that the bootloader cannot really set a sane default for all.
So introduce a top-level driver for the grf that handles these
settings that need to be a certain way but nobody cares about.
Other needed settings might surface in the future and can then
be added here, but only as a last option. Ideally general GRF
settings should be handled in the driver needing them.

"Highlights include:
- Support for the kexec_file_load() syscall, which is a prereq for
secure and trusted boot.
- Prevent kernel execution of userspace on P9 Radix (similar to
SMEP/PXN).
- Sort the exception tables at build time, to save time at boot, and
store them as relative offsets to save space in the kernel image &
memory.
- Allow building the kernel with thin archives, which should allow us
to build an allyesconfig once some other fixes land.
- Build fixes to allow us to correctly rebuild when changing the
kernel endian from big to little or vice versa.
- Plumbing so that we can avoid doing a full mm TLB flush on P9
Radix.
- Initial stack protector support (-fstack-protector).
- Support for dumping the radix (aka. Linux) and hash page tables via
debugfs.
- Fix an oops in cxl coredump generation when cxl_get_fd() is used.
