hw/intc/arm_gicv3: Fix ICC register tracepoints

Fix some problems with the tracepoints for ICC register reads
and writes:
 * tracepoints for ICC_BPR<n>, ICC_AP<n>R<x>, ICC_IGRPEN<n>,
   ICC_EIOR<n> were not printing the <n> that indicated whether
   the access was to the group 0 or 1 register
 * the ICC_IGREPEN1_EL3 read function was not actually calling
   the associated tracepoint
 * the ICC_BPR<n> write function was incorrectly calling the
   tracepoint for ICC_PMR writes
