Convert switch register accesses in the phylink MAC configuration and
link callbacks to the shared regmap. Use regmap_update_bits() for masked
updates and regmap_read()/regmap_write() when assembling full force-mode
values.
The callbacks are void, so leave regmap return values unchecked to match
the existing callback behavior.
