Changes in version 2:
- removed the R8A77980 part, renamed the patch, and updated the description;
- renamed the RPC-IF node to "spi@ee200000";
- updated the R8A77970 RPC-IF "compatible" prop to match the bindings;
- split the 1st region in the "reg"/"reg-names" props for the WBUF registers;
- refreshed the patch.
