Since FIXED_PHY depends on PHYLIB, PHYLIB needs to be set to avoid
a kconfig warning:

WARNING: unmet direct dependencies detected for FIXED_PHY
  Depends on [n]: NETDEVICES [=y] && PHYLIB [=n]
  Selected by [y]:
  - LAN743X [=y] && NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_MICROCHIP [=y] && PCI [=y] && PTP_1588_CLOCK_OPTIONAL [=y]
