t23x: nv-soc: Add display fb carveout DT node

Browse Source 
- Add display fb carveout region node to the list of
reserved memory regions
- UEFI updates the "reg" property with base address and
size of display fb carveout memory region and "status"
of display fb carveout region node to "okay" if UEFI
initializes display.
- keeping the fb carveout region node disabled by default
such that it is enabled by UEFI dynamically only when UEFI
initializes display and handsoff display fb carveout region
to kernel.
- add display fb reserved region node handle to display DT node
for unity mapping of display reserved region when SMMU driver
comes up in kernel only if display fb carveout region DT node
is enabled by UEFI.
