xen/arm: vgic-v3: Correctly handle GICD_CTLR

As backward GICv2 compatibility is not supported in the vGICv3 driver,
the bit ARE_NS is RAO/WI.

Furthermore, when ARE_NS is set, the guest can only modify EnableGrp1A.

At same time take the vgic_lock to write into domain.arch.vgic.ctrl. It
was already taken during read.
