Revert "kernel-arch.bbclass: add arm64 support to U-Boot architecture map"
This reverts commit
0b891265716c414ade29d587fc1a3c4ea7beadbe.
U-Boot does support AArch64, this however was only added to newer
versions of U-Boot and at the time of this original commit the U-Boot in
OE-Core did not support the 'arm64' architecture. OE-Core now has a
newer version of U-Boot for the mkimage recipe and thus supports the
'arm64' architecture.
