hw/intc/arm_gic: Make per-cpu GICH memory regions 0x200 bytes large

Browse Source 
Reduce the size of the per-cpu GICH memory regions from 0x1000
to 0x200. The registers only cover 0x200 bytes, and the Cortex-A15
wants to map them at a spacing of 0x200 bytes apart. Having the
region be too large interferes with mapping them like that, so
reduce it.
