Bits for undefined preemption levels are RAZ/WI.
Note that this differs from a CPU's view of the APRs on hardware in which
a GIC without the security extensions expose group 0 and group 1 active
priorities in separate register groups, whereas we show a combined view
similar to GICv2's GICH_APR.
For historical reasons and to provide ABI compatibility with userspace we
export the GICC_PMR register in the format of the GICH_VMCR.VMPriMask
field in the lower 5 bits of a word, meaning that userspace must always
