Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts. They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.
Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h
The patch is outcome of the discussion in below thread:

For CONFIG_THUMB2_KERNEL, the existing definition of do_wfi() will
insert invalid code into the instruction stream.
Any assembler which can assemble Thumb-2 is guaranteed to accept
the "wfi" mnemonic, so for the Thumb-2 case, just use the mnemonic.
The ARM case is left as-is.

Every architecture using the GIC has a gic_cpu_base_addr pointer for
GIC 0 for their entry assembly code to use to decode the cause of the
current interrupt. Move this into the common GIC code.

This patch adds cpu hotplug support for OMAP4430. Only CPU inactive
state is supported as a low power state in the basic hot-plug support

This patch moves OMAP4 soc specific code from 4430sdp board file.
The change is necessary so that newer board support can be added
with minimal changes. This will be also problematic for
multi-board, multi-omap builds.
