It is easier to manage one array of MMIO MR rather
than one per vCPU.

hw/intc/loongson_ipi: Provide per core MMIO address spaces

The real IPI hardware have dedicated MMIO registers mapped into
memory address space for every core. This is not used by LoongArch
guest software but it is essential for CPU without IOCSR such as
Loongson-3A1000.

Implement it with existing infrastructure.
