regmap: mdio: Clean up invalid clause-22 addresses
Currently a regmap configuration for regmap-mdio must have a register
address width of 5 bits (cf. clause-22 register access). This is not
enforced on the provided register addresses, which would enable
clause-45 MDIO bus access, if the right bit packing is used.
Prevent clause-45 access, and other invalid addresses, by masking the
provided register address.
