hw/intc/loongson_ipi: Remove num_cpu from loongson_ipi_common
With mips64 loongson ipi, num_cpu property is used. With loongarch ipi, num_cpu can be acquired from possible_cpu_arch_ids. Here remove num_cpu setting from loongson_ipi_common, and this piece of code is put into loongson and loongarch ipi separately.
