Modified Files:
        src/sys/arch/arm/cortex: gicv3.c

Log Message:
Change how we detect secure vs non-secure access.

Write 0xff to ICC_PMR_EL1 and read back how many bits are implemented,
then do the same with a GICD_IPRIORITYR<n> priority value field.

If the values differ, assume we have a shifted view of IPRIORITYR.
