This is preparation for supporing PM6125. The HFSMPS is a BUCK type regulator with subtype 0x0a, same as the existing HFS430 regulator. Even though the HFSMPS and HFS430 share a register layout, the HFSMPS has different mode values (BYPASS, RETENTION and LPM are one lower). I'm expecting future regulators (higher revision) with the same type and subtype to share mode values of HFSMPS, so revisions 4 (found on pm6125) and up use the new ops. The inspiration of this is taken from [1].
