Why does this all need to be under arch/arm64? The GTDT really isn't
architecture-specific, so I'd *much* rather it was parsed in the driver code
itself, like we already do for the architected timer. The GIC is an
exception because it's in the MADT, which we need to parse in the arch code
to configure SMP properly.
