uio: add support to map SRAM to userspace
This driver config the L2 Cache to be SRAM mode and map the SRAM to user
space. The size and the address of SRAM are passed in the U-boot command
line as format: cache-sram=addr,size.
Please notice that this driver is exclusive with config FSL_85XX_CACHE_SRAM.
