On LoongArch system, there is iocsr address space simliar system io
address space on x86. And each cpu has its separate iocsr address space now,
with this patch, iocsr address space is changed with per-board, and
MemTxAttrs.requester_id is used to differentiate cpu cores.

Changes in v2:
1. Add num-cpu property for extioi interrupt controller
2. Add post_load support for extioi vmstate to calculate sw_ipmap/sw_coremap
