hw/intc/arm_gic: Remove the definition of NUM_CPU

arm_gic.c retrieves CPU number using either NUM_CPU(s) or s->num_cpu.
Such mixed-uses make source code inconsistent. This patch removes
NUM_CPU(s), which was defined for MPCore tweak long ago, and instead
favors s->num_cpu. The source is more consistent after this small tweak.
