[PATCH 4/9] ARM: omap: add include guard for soc.h

[Arnd Bergmann]

Commit e4c060db "ARM: OMAP: Split plat/cpu.h into local soc.h for
mach-omap1 and mach-omap2" moved the bulk of "plat/cpu.h" into "cpu.h"
but did not add an include guard for the new file that was present
in the old one. There are cases where the file is indeed included
multiple times, probably by accident, but adding the include
guard ensures that this has no further consequences.

Without this patch, building allmodconfig results in lots of warnings like:
