u-boot: Map arm64 into map for u-boot dts installation
While arm64 is a valid UBOOT_ARCH (according to mkimage -A) u-boot
keeps arm64 specific dts under 'arch/arm' directory.
As the result the recipe tries to install arch/arm64 (if UBOOT_DTB
was specified) and fails with [1]. Remapping "arm64" to "arm" to fix this
issue.
