arm_gic: Add GICC_APRn state to the GICState
The GICC_APRn registers are not currently supported by the ARM GIC v2.0
emulation.  This patch adds the missing state.

Note that we also change the number of APRs to use a define GIC_NR_APRS
based on the maximum number of preemption levels.  This patch also adds
RAZ/WI accessors for the four registers on the emulated CPU interface.
