hw/loongarch/virt: Set max 256 cpus support on loongarch virt machine
Add separate macro EXTIOI_CPUS for extioi interrupt controller, extioi
only supports 4 cpu. And set macro LOONGARCH_MAX_CPUS as 256 so that
loongarch virt machine supports more cpus.
Interrupts from external devices can only be routed cpu 0-3 because
of extioi limits, cpu internal interrupt such as timer/ipi can be
triggered on all cpus.
