[PATCH] Modify raspberrypi mm_config_table to map GPIO and registers.

Changes include reverting back to setting all page-table section entries as invalid and modify mm_config_table to apply the correct memory attributes for raspbberypi memory sections at startup. The newly added entry at mm_config_table maps raspberrypi GPIO and other registers found at raspberrypi
