Message:

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.h
