sram_params.sram_size and sram_params.sram_offset were unsigned.
If get_cache_sram_size() or get_cache_sram_offset() returns error code
then it is not seen to the caller. Made sram_size and sram_offset signed.

Get rid of old users of of_platform_driver in arch/powerpc. Most
of_platform_driver users can be converted to use the platform_bus
directly.

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>
