The VGA memory region is always from the top of RAM. On this board, that
is 0x80000000 + 0x20000000 - 0x01000000 = 0x9f000000.
This was not an issue in practice as the region is "reserved" by the
vendor's u-boot reducing the amount of available RAM, and the only user
is the host VGA device poking at RAM over PCIe. That is, nothing from
the ARM touches it.
It is worth fixing as developers copy existing device trees when
building their machines, and the XDMA driver does use the memory region
from the ARM side.
