Ronak Desai 4730df02cf uboot: arm64 arch build support 
For a 64bit arm architecture, Buildroot uses arm64 terminology and
from the top-level Makefile KERNEL_ARCH is set to arm64 which is then
passed to the uboot build.  This causes a compilation issue as uboot
uses the top-level system architecture as it's $(ARCH).  So
arch/$(ARCH)/Makefile doesn't work with arm64 unless we adjust the
arch.

 - rewrap commit message text.
 - simplify comment in the code.]
