Add bindings for the regulators found in the MediaTek MT6316 PMIC, usually found in board designs using the MT6991 Dimensity 9400 and on MT8196 Kompanio SoC for Chromebooks. This chip is fully controlled by SPMI and has multiple variants providing different phase configurations.

Btw, sorry about those Link: tags, those were completely unwanted... they slipped through while using b4 and I forgot to remove them. I'll wait for any feedback or tags and will resend the series with those tags removed. Thanks, Angelo
