Acked + applied. I reworded the commit message a bit in an attempt to
make it clearer:

   xen/arm: Handle translated addresses for hardware domains in GICv2
    
    Translated addresses (in d->arch.vgic.{c,d}base) are bus addresses
    which are not always correct in the context of a subnode in the DTB
    exposed to domain 0 since they would then be subject to retranslation.
    
    Copy the original addresses from DT directly to get the original
    untranslated reg property which will give same d->arch.vgic.{c,d}base
    values once translated again by the guest.

I hope that is ok.
