  hw/intc/loongarch_ipi: Bring back all 4 IPI mailboxes

As per "Loongson 3A5000/3B5000 Processor Reference Manual",
Loongson 3A5000's IPI implementation have 4 mailboxes per
core.

However, in 78464f023b54 ("hw/loongarch/virt: Modify ipi as
percpu device"), the number of IPI mailboxes was reduced to
one, which mismatches actual hardware.

It won't affect LoongArch based system as LoongArch boot code
only uses the first mailbox, however MIPS based Loongson boot
code uses all 4 mailboxes.
