arm64: zynqmp: Setup MMU map for DDR at run time
This patch fills the MMU map for DDR at run time based on information read
from Device Tree or automatically detected from static configuration.
The patch is needed because for systems which has for example 1GB of memory
but MMU map is 2GB there could be spurious accesses which was seen in past
when mapping is not fitting with actual memory installed.
