[PULL 3/8] hw/intc/loongson_ipi: Remove num_cpu from loongson_ipi_common

[Bibo Mao]

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.
