arm64: zynqmp: Provide a config to not map DDR region in MMU table

DDR less systems are possible for configuration like mini qspi
and making DDR region as normal memory may cause speculative
access which results u-boot hang if DDR is absent. So, this
patch fixes the issue by not making DDR memory region
entry into MMU table.

Future solution is to prepare MMU table per memory node in dts instead
of hard code DDR addresses.
