ARM: OMAP2: Dynamic allocator for GPMC memory space
Add support for assigning memory regions dynamically to peripherals
attached to GPMC interface. Platform specific code should now call
gpmc_cs_request to get a free GPMC memory region instead of using
a fixed address.
Make the H4 and Apollon platform initialization use the new API.
