In order to handle errata I688, a page of sram was reserved by doing a static iotable map. Now that we use gen_pool to manage sram, we can completely remove all of these static mappings and use gen_pool_alloc() to get the one page of sram space needed to implement errata I688. omap_bus_sync will be NOP until SRAM initialization happens.
