The issue is that FDT and ACPI are two mechanisms for providing the same
data. If we have 64-bit ARM hardware that can be configurd with both
then we'll end up with two sets of drivers - one using the FDT bindings,
one using the ACPI bindings. We should consolidate those before landing
an architecture that encourages this kind of divergence.
