fdt: Properly handle "no-map" field in the memory region

Browse source 
[ Upstream commit 86588296acbfb1591e92ba60221e95677ecadb43 ]

Mark the memory region with NOMAP flag instead of completely removing it
from the memory blocks. That makes the FDT handling consistent with the EFI
memory map handling.
