hw/arm_gic: Correctly restore nested irq priority
Upon activating an interrupt, set the corresponding priority bit in the
APR/NSAPR registers without touching the currently set bits. In the event
of nested interrupts, the GIC will then have the information it needs to
restore the priority of the pre-empted interrupt once the higher priority
interrupt finishes execution.
