armv8: K3: am65x: Update DDR address regions in MMU table

The A53 U-Boot code can load and boot the MCU domain R5F cores (either a
single core in LockStep mode or 2 cores in Split mode) to achieve various
early system functionalities. Change the memory attributes for the DDR
regions used by the remote processors so that the cores can see and
execute the proper code loaded by U-Boot.

These regions are currently limited to 0xa0000000 to 0xa2100000 as per
the DDR carveouts assigned for these R5F cores in the overall DDR memory
map.
