Subject: [PATCH 06/16] net: dsa: mt7530: use unlocked regmap accessors
Instead of wrapping the locked register accessor functions, use the
unlocked variants and add locking wrapper functions to let regmap
handle the locking.
This is a preparation towards being able to always use regmap to
access switch registers instead of open-coded accessor functions.
