Simplify .match_phy_device OP by using a generic function and using the
new phy_id PHY driver info instead of hardcoding the matching PHY ID
with new variant for macsec and no_macsec PHYs.

Also make use of PHY_ID_MATCH_MODEL macro and drop PHY_ID_MASK define to
introduce phy_id and phy_id_mask again in phy_driver struct.
