This fixes a build break that was probably introduced with the removal
of -Wa,-me500 (commit f49596a4cf4753d13951608f24f939a59fdcc653), where
the assembler refuses to recognize SPRG4-7 with a generic PPC target.

This problem belongs to the core synchronization issues.
The cpu1 already updated spin_table values, but bootcore cannot get
this value in time.
After bootcpu hibiernation restore the pages. we are now running
with the kernel data of the old kernel fully restored. if we reset
the non-bootcpus that will be reset cache(tlb), the non-bootcpus
will get new address(map virtual and physical address spaces).
but bootcpu tlb cache still use boot kernel data, so we need to
invalidate the bootcpu tlb cache make it to get new main memory data.
log:
Enabling non-boot CPUs ...
smp_85xx_kick_cpu: timeout waiting for core 1 to reset
smp: failed starting cpu 1 (rc -2)
Error taking CPU1 up: -2

This is started as swsusp_32.S modifications, but the amount of #ifdefs
made the whole file horribly unreadable, so let's put the support into
its own separate file.
The code should be relatively easy to modify to support 44x BookEs as
well, but since I don't have any 44x to test, let's confine the code to
FSL BookE. (The only FSL-specific part so far is 'flush_dcache_L1'.)
