hw/intc/arm_gicv3: Introduce redist-region-count array property

Browse source 
To prepare for multiple redistributor regions, we introduce
an array of uint32_t properties that stores the redistributor
count of each redistributor region.

Non accelerated VGICv3 only supports a single redistributor region.
The capacity of all redist regions is checked against the number of
vcpus.

Machvirt is updated to set those properties, ie. a single
redistributor region with count set to the number of vcpus
capped by 123.
