dev-arm: Limit number of max PE in GICv3 to 128

This is needed since there is a problem in the memory layout of
VExpress_GEM5_V2 as it is: having 256KB pages is creating overlapping
regions when reserving space for 256 PEs.

GICv3 redistributors: 0x2c010000 - 0x30010000
PCI regions: 0x30000000 - 0x40000000

We fix this by cutting down the number of supported PEs to 128
