powerpc/85xx: add cache-sram support
It adds cache-sram support in P1/P2 QorIQ platforms as under:
* A small abstraction over powerpc's remote heap allocator
* Exports mpc85xx_cache_sram_alloc()/free() APIs
* Supports only one contiguous SRAM window
* Drivers can do the following in Kconfig to use these APIs
"select FSL_85XX_CACHE_SRAM if MPC85xx"
* Required SRAM size and the offset where SRAM should be mapped must be
provided at kernel command line as :
cache-sram-size=<value>
cache-sram-offset=<offset>
