ARM: OMAP: PM: Add support to allocate the memory for secure RAM
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.
