net: phy: nxp-c45-tja11xx: use get_features

PHY_BASIC_T1_FEATURES are not the right features supported by TJA1103
anymore.
For example ethtool reports:
	[root@alarm ~]# ethtool end0
	Settings for end0:
	        Supported ports: [ TP ]
	        Supported link modes:   100baseT1/Full
	                                10baseT1L/Full

10baseT1L/Full is not supported by TJA1103 and supported ports list is
not completed. The PHY also have a MII port.

genphy_c45_pma_read_abilities implementation can detect the PHY features
and they look like this.
[root@alarm ~]# ethtool end0
Settings for end0:
        Supported ports: [ TP    MII ]
