ARM: cpu hotplug: remove majority of cache flushing from platforms
Remove the majority of cache flushing calls from the individual platform
files. This is now handled by the core code.

ARM: consolidate pen_release instead of having per platform definitions
Almost each SMP platform defines pen_release to manage booting secondary
CPUs. This of course clashes with the single zImage effort.
Add the pen_release definition to the ARM SMP code, and remove all others.
This should only be used by platforms which lack any kind of CPU power
management...

ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMP
It turns out that the logical CPU mapping is useful even when !CONFIG_SMP
for manipulation of devices like interrupt and power controllers when
running a UP kernel on a CPU other than 0. This can happen when kexecing
a UP image from an SMP kernel.
In the future, multi-cluster systems running AMP configurations will
require something similar for mapping cluster IDs, so it makes sense to
decouple this logic in preparation for this support.

ARM: versatile: convert logical CPU numbers to physical numbers
This patch uses the new cpu_logical_map() macro for converting logical
CPU numbers into physical numbers when dealing with the pen_release
variable in the SMP boot and CPU hotplug paths.

ARM: 7064/1: vexpress: Use wfi macro in platform_do_lowpower.
Current Versatile Express CPU hotplug code includes a hardcoded WFI
instruction, in ARM encoding. When the kernel is compiled in Thumb-2
mode, this is invalid and causes the machine to hang hard when a CPU
is offlined.
Using the wfi macro (which uses the appropriate assembler mnemonic)
causes the correct instruction to be emitted in either case. As a
consequence of this change, an apparently vestigial "cc" clobber is
dropped from the asm (the macro uses "memory" only).
