Subject: [PATCH 5/5] ArmVExpressPkg: add support for embedding DTBs for AArch64
variants
If DTB_DIR=<path> is set during the build, incorporate DTBs from that path for
all AArch64 FVP platform variants so that they can be loaded straight from the
firmware image instead of from a file system. This relieves a user of having to
keep a DTB file with the right name in the working directory of the model.
