net: phy: air_phy_lib: Factorize BuckPBus register accessors
In preparation of Airoha AN8801R PHY support, move the BuckPBus
register accessors and definitions, present in air_en8811h driver,
into the Airoha PHY shared code (air_phy_lib), so they will be usable
by the new driver without duplicating them.
