OF shouldn't be automatically selected in the arm64/Kconfig.  It should
have a config
parmaeter like other archs as mips and arm.  I can submit a patch so it
functions the
same way as other archs so it is not always selected.  It will be good
to add a USE_OF
config options like the other archs (or simply remove the select from
the Kconfig and choose OF directly in the defconfig.
This will have the added benefit of doing away with OF support when its
not needed on an ARM64 platform.  ACPI is already not automatically
selected for all ARM64 platforms, nor should devicetree.
