[U-Boot] [PATCH v4 23/26] Makefile: use "arm64" architecture for U-Boot image files

At the moment we use the arch/arm directory for arm64 boards as well,
so the Makefile will pick up the "arm" name for the architecture to use
for tagging binaries in U-Boot image files.
Differentiate between the two by looking at the CPU variable being defined
to "armv8", and use the arm64 architecture name on creating the image
file if that matches.
