iommu/arm-smmu: Abstract GR0 accesses

Browse source

Clean up the remaining accesses to GR0 registers, so that everything is
now neatly abstracted. This folds up the Non-Secure alias quirk as the
first step towards moving it out of the way entirely. Although GR0 does
technically contain some 64-bit registers (sGFAR and the weird SMMUv2
HYPC and MONC stuff), they're not ones we have any need to access.
