This patch updates memory region:

  - After changes, the new map of the m3ulcb board on R8A7796 SoC
    Bank0: 1GiB RAM : 0x000048000000 -> 0x0007fffffff
    Bank1: 1GiB RAM : 0x000600000000 -> 0x0063fffffff

  - Before changes, the old map looked like this:
    Bank0: 1GiB RAM : 0x000048000000 -> 0x0007fffffff

BTW, this means M3ULCB has a different R-Car M3 SiP than Salvator-X,
with half the RAM?
