Add a 'pm_sram_code' reserved region to the ocmcram node to be exposed by the mmio-sram driver as a pool but also mark it protect-exec so that it can run code copied to it using sram_exec_copy. Add another 'pm_sram_data' reserved region to the ocmcram node to act as the data space for any code running from the 'pm_sram_code' region that is exposed as a regular pool.
