omap_secure_ram_reserve_memblock is stubbed for OMAP1,2 only builds using a
ifdef check. But this results in adding CONFIG_ARCH_OMAPxx checks for
future socs that use the real function. So move this to common.c file and
call it __weak.

arm_memblock_steal() is not suppose to be used outside ->reserve callback.
OMAP barrier errata code was using it outside reserve callback and hence
it was broken.
Move the allocation as part of ->reserve callback to fix the it.

OMAP2 devices doesn't have the security support but the security support
was getting built because of OMAP2PLUS. Don't build security code for
OMAP2 devices.
While at it, fix the secure-common line in the Makefile to use tabs
instead of spaces.

Allocate the memory to save secure ram context which needs
to be done when MPU is hitting OFF mode.
The ROM code expects a physical address to this memory
and hence use memblock APIs to reserve this memory as part
of .reserve() callback. Maximum size as per secure RAM requirements
is allocated.
To keep omap1 build working, omap-secure.h file is created
under plat-omap directory.
