Peter Maydell a2e2d7fc46 hw/intc/arm_gicv3: Fix secure-GIC NS ICC_PMR and ICC_RPR accesses
If the GIC has the security extension support enabled, then a
non-secure access to ICC_PMR must take account of the non-secure
view of interrupt priorities, where real priorities 0x00..0x7f
are secure-only and not visible to the non-secure guest, and
priorities 0x80..0xff are shown to the guest as if they were
0x00..0xff. We had the logic here wrong:
 * on reads, the priority is in the secure range if bit 7
   is clear, not if it is set
 * on writes, we want to set bit 7, not mask everything else

Our ICC_RPR read code had the same error as ICC_PMR.

(Compare the GICv3 spec pseudocode functions ICC_RPR_EL1
and ICC_PMR_EL1.)
