From: Adam Johnston <adam.johnston@arm.com>
This patch, from N1SDP 2022-R1, adds support to parse NT_FW_CONFIG to EDK2
platform code for the N1SDP. This is required to fix aborts seen when testing
virtual memory after enabling trusted boot.
NT_FW_CONFIG DTB contains platform information passed by TF-A boot stage.
This information is used for virtual memory map generation during PEI phase
and passed on to DXE phase as a HOB, where it is used in
ConfigurationManagerDxe.
