Then add support to access Clause 45 phy registers. Both commits are tested on the Bananapi BPi-R64 board having MediaTek MT7531BE DSA gigE switch using clause 22 MDIO and Ubiquiti UniFi 6 LR access point having Aquantia AQR112C PHY using clause 45 MDIO. v4: clean-up return values and types, split into two commits v3: return -1 instead of 0xffff on error in _mtk_mdio_write v2: use MII_DEVADDR_C45_SHIFT and MII_REGADDR_C45_MASK to extract device id and register address. Unify read and write functions to have identical types and parameter names where possible as we are anyway already replacing both function bodies.
