hw/intc/arm_gic: Change behavior of IAR writes

Browse source 
Grouping (GICv2) and Security Extensions change the behavior of IAR
reads. Acknowledging Group0 interrupts is only allowed from Secure
state and acknowledging Group1 interrupts from Secure state is only
allowed if AckCtl bit is set.

[PMM: simplify significantly by reusing the existing
 gic_get_current_pending_irq() rather than reimplementing the
 same logic here]
