This patch updates memory region:
- After changes, the new map of the Salvator-X board on R8A7796 SoC
Bank0: 2GiB RAM : 0x000048000000 -> 0x000bfffffff
Bank1: 2GiB RAM : 0x000600000000 -> 0x0067fffffff
- Before changes, the old map looked like this:
Bank0: 2GiB RAM : 0x000048000000 -> 0x000bfffffff

Note: Depending on firmware version, this patch may not make a
difference at all!
Indeed, U-Boot may already add the second memory region to the "reg"
property of the first memory node in DT, regardless of the presence of a
second memory node. Fortunately Linux handles duplicate memory regions
just fine...
