ratp: implement generic command support ...

The RATP implementation now allows executing generic commands with a
binary interface: binary requests are received and binary responses
are returned.

Each command can define its own RATP request contents (e.g. to specify
command-specific options) as well as its own RATP response contents
(if any data is to be returned).

Each command is associated with a pair of numeric unique request and
response IDs, and for easy reference these IDs are maintained in the
common ratp_bb header. Modules may override generic implemented
commands or include their own new ones (as long as the numeric IDs
introduced are unique).

efi: move x86 clocksource to device/driver ...

so we can dynamicly register the device

As we may need to use HW IP for clocksource.

As on EFI we could use Timestamp GUID if present (Not often the case as it's
not even enabled by default on any Target on EDK II not even OVMF)

Or if we choose we could use a Simulated Timestamp driver that work on Event

arch: refresh defconfigs ...

The defconfig files are long untouched and a
make xy_defconfig; make savedefconfig usually generates quite
a different looking file. Refresh them to make it easier to generate
patches against the configs using
make xy_defconfig; make menuconfig; make savedefconfig

This has been done with the following script.

for a in arch/*; do
	arch=$(basename $a)
	for c in $a/configs/*; do
		config=$(basename $c)

	export ARCH=$arch
	make $config && make savedefconfig && mv defconfig $c
	done
done

rework remap_range ...

remap_range is for remapping regions with different cache attributes.
It is implemented for ARM and PowerPC only, the other architectures only
provide stubs.
Currently the new cache attributes are passed in an architecture specific
way and the attributes have to be retrieved by calls to
mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags().
Make this simpler by providing architecture independent flags which can
be directly passed to remap_range()
Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function.
The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture
has as default. the arch_can_remap() function returns true if the
architecture can change the cache attributes, false otherwise. This
allows the memtest code to better find out what it has to do.

restart: replace reset_cpu with registered restart handlers ...

This replaces the reset_cpu() function which every SoC or board must
provide with registered handlers. This makes it possible to have multiple
reset functions for boards which have multiple ways to reset the machine.
Also boards which have no way at all to reset the machine no longer
have to provide a dummy reset_cpu() function.

The problem this solves is that some machines have external PMICs or
similar to reset the system which have to be preferred over the
internal SoC reset, because the PMIC can reset not only the SoC but also
the external devices.

To pick the right way to reset a machine each handler has a priority. The
default priority is 100 and all currently existing restart handlers are
registered with this priority. of_get_restart_priority() allows to retrieve
the priority from the device tree which makes it possible for boards to
give certain restart handlers a higher priority in order to use this one
instead of the default one.

kbuild: move asm-offsets.h rule to ./Kbuild ...

Currently, MIPS is the only architecture that needs
include/generated/asm-offsets.h, but we have got ./Kbuild file now.

It is a good reason to move asm-offsets.h rule from arch/mips/Makefile
to ./Kbuild and add dummy asm-offsets.c for the other architectures.
asm-offsets.h would be useful for all the architectures.

This commit does not implement include/generated/bounds.h,
but if necessary, it is easy to implement it.

We have many variants of the same bitops.h file. Consistently
use the same file for all architectures which completely use
the generic bitops versions.

Some architectures had static inline versions of functions
identically to the generic versions, these are removed and
the generic versions are used directly now.

Also several architectures depend on the generic find_*_bit
functions but didn't have the GENERIC_FIND_NEXT_BIT Kconfig
option selected. This is added where needed.
