Add the support to build the DT of internal SoCs without adding direct name from the Makefile but passed from the make command. This will help to make the DT of all internal SoCs. Bug 4197981 Change-Id: I03c55cef5903a814a20d6f86d8ecfffe552daf29 Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/2982406 GVS: Gerrit_Virtual_Submit <buildbot_gerritrpt@nvidia.com>
