This function is only used for DOM0 where we can hardly differ from the host GIC. Actually, at some point, we may need to copy the reg from the host DT as we do from GICv2 (see 5009babad9bfac9c88706e366bed3f2fdf4ed3ca "xen/arm: Handle translated addresses for hardware domains in GICv2"). It may be worth to rename the callback to make clear that this is for the hardware domain (i.e DOM0) only.
