The RSK+ setup code was doing some pretty dubious things with
parse_mtd_partitions() in order to populate the physmap-flash map
platform data. The physmap-flash driver contains all of the functionality
that we require already, so simply drop the special casing and pad out
the platform data accordingly.

The cache functions lock out interrupts for long periods; this patch
reduces the impact when operating on large address ranges. In such
cases it will:
- Invalidate the entire cache rather than individual addresses.
- Do nothing when flushing the operand cache in write-through mode.
- When flushing the operand cache in write-back mdoe, index the
  search for matching addresses on the cache entires instead of the
  addresses to flush

Note: sh2a__flush_purge_region was only invalidating the operand
cache, this adds flush.

This patch contains r8a7779 SMP support V3 - now including
CPU hotplug offine and online support. The r8a7779 power
domain code is tied together with SMP glue code which allows
us to control the power domains via CPU hotplug.

At this point the kernel boots with the 4 Cortex-A9 cores in
SMP mode and all CPU cores except CPU0 can be hotplugged.

The code in platsmp.c is quite far from pretty, but it is
kept like that intentionally to avoid creating layers of
code that will go away in the near future anyway. The code
needs to be updated when some per-SoC handling code will be
added to the ARM architecture, see the following patch for
more information:

but only the older SA_NOMASK.  Since SA_NOMASK is the historical name for
SA_NODEFER, add SA_NODEFER and copy what other architectures do by making
SA_NOMASK a synonym for SA_NODEFER.

Randomization of PIE load address is hard coded in binfmt_elf.c for X86
and ARM.  Create a new Kconfig variable
(CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE) for this and use it instead.  Thus
architecture specific policy is pushed out of the generic binfmt_elf.c and
into the architecture Kconfig files.

X86 and ARM Kconfigs are modified to select the new variable so there is
no change in behavior.  A follow on patch will select it for MIPS too.

Add power domain control support for the r8a7779 SoC V2.

This adds support for 4 power domains for I/O Devices
together with code that can be used for CPU cores as well.

The only out of the ordinary experience is the need for
ioremap() of SYSC registers. Because of that we need to
execute some init function before setting up the domains.
