ARM: OMAP2+: raw read and write endian fix
All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.
Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

ARM: cpu hotplug: remove majority of cache flushing from platforms

ARM: OMAP4+: Remove the un-necessary cache flush from hotplug code
This was added with intial port where OMAP PM support wasn't existing
and only simple WFI based hooks were used.
This should have been cleaned up while adding the PM support but some
how fall through cracks.
So remove the cache flush code which is no longer needed now.

ARM: OMAP5: Add the WakeupGen IP updates
OMAP4 and OMAP5 share same WakeupGen IP with below few udpates on OMAP5.
- Additional 32 interrupt support is added w.r.t OMAP4 design.
- The AUX CORE boot registers are now made accessible from non-secure SW.
- SAR offset are changed and PTMSYNC* registers are removed from SAR.
Patch updates the WakeupGen code accordingly.

ARM: OMAP: Fix section mismatch warning for platform_cpu_die()
WARNING: vmlinux.o(.text+0x226d0):
Section mismatch in reference from the function
platform_cpu_die() to the function .cpuinit.text:omap4_hotplug_cpu()
The function platform_cpu_die() references
the function __cpuinit omap4_hotplug_cpu().
This is often because platform_cpu_die lacks a __cpuinit
annotation or the annotation of omap4_hotplug_cpu is wrong.
Thanks to Russell King for suggesting to use __ref instead of
the initial (and wrong) approach to use __cpuinit.

ARM: 7159/1: OMAP: Introduce local common.h files
As suggested by Russell King - ARM Linux <linux@arm.linux.org.uk>,
there's no need to keep local prototypes in non-local headers.
Add mach-omap1/common.h and mach-omap2/common.h and move the
local prototypes there from plat/common.h and mach/omap4-common.h.

ARM: CPU hotplug: remove bug checks in platform_cpu_die()
platform_cpu_die() is entered from the CPU's own idle thread, which
can not be migrated to other CPUs. Moreover, the 'cpu' argument
comes from the thread info, which will always be the 'current'
CPU. So remove this useless bug check.

ARM: CPU hotplug: move cpu_killed completion to core code
We always need to wait for the dying CPU to reach a safe state before
taking it down, irrespective of the requirements of the platform.
Move the completion code into the ARM SMP hotplug code rather than
having each platform re-implement this.
