This series patchset is to clean up with memory regions of loongarch pch
pic interrupt controller. Originally there are three iomem regions:
iomem32_low, iomem8, iomem32_highm. Since these regions only support
4 bytes/1 byte/4 bytes access, it is divided into three regions.

Now it is merged into one region, this regions supports 1/2/4/8 bytes
access.

Patch 1-6 is to replace register name, no function change.
Patch 7-16 is to use unifed memory region iomem, and supports 1/2/4/8
bytes access with read/write ops for this region, and merge three
regions above into one.

---
  v2 ... v3:
    1. Set address aligned with 8 bytes in memory region function
       pch_pic_read() and pch_pic_write(), and only compare register
       base address with 8 bytes aligned one.
    2. Replace 0xff/0xffff with UCHAR_MAX/USHRT_MAX.

  v1 ... v2:
    1. Add 1/2/4/8 bytes access support with memory region read and
       write ops.
    2. Merge three memory regions iomem32_low, iomem8 and iomem32_high
       into one region iomem.
    3. Merge trace functions for ops in above three memory regions into
       one trace function
