hw/loongarch/virt: Set iocsr address space per-board rather than percpu

LoongArch system has iocsr address space, most iocsr registers are
per-board, however some iocsr register spaces banked for percpu such
as ipi mailbox and extioi interrupt status. For banked iocsr space,
each cpu has the same iocsr space, but separate data.

This patch changes iocsr address space per-board rather percpu,
for iocsr registers specified for cpu, MemTxAttrs.requester_id
can be parsed for the cpu. With this patches, the total address space
on board will be simple, only iocsr address space and system memory,
rather than the number of cpu and system memory.

There are two interface pairs for MemoryRegionOps, read/write and

emulation since initial cpu can be parsed from attrs.requester_id.

And requester_id can be overrided for IOCSR_IPI_SEND and mail_send

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.
