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.

v3 ... v4:
1. Use uint8_t rather than bitfield in packed structure since there is
different definition about bitfield between gcc and MSVC.
2. Rebase patch based on latest version.
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
