[PATCH v4 0/3] i3c: dw: Add apb reset support

Add support of apb reset which is to reset the APB interface.
The first patch is to document the exisiting reset dt-binding. 2nd patch
is to add apb reset dt-binding. The last patch is to add apb reset
support.

NOTE: to align with "core_rst", the new added apb reset is named as
"apb_rst", IOW, the reset names: "core_rst" + "apb_rst". I can modify
it if maintainers prefer "core_rst" + "apb"

Since v3:
  - back to v2, I.E keep the "_rst" suffix, since removing it is an
    ABI breakage.

Since v2:
  - remove "_rst" suffix

Since v1:
  - add dt-binding
