net: phy: nxp-c45-tja11xx: use phylib master/slave implementation

commit cccf8b1a21be7025b4fefb98863792eb529ba867 from
https://github.com/nxp-auto-linux/linux



Remove the custom implementation of master/save setup and read status
and use genphy_c45_config_aneg and genphy_c45_read_status since phylib
has support for master/slave setup and master/slave status.
