net: lan743x: select FIXED_PHY

The blamed commit introduces usage of fixed_phy_register() but
not a corresponding dependency on FIXED_PHY.

This can result in a build failure.

 s390-linux-ld: drivers/net/ethernet/microchip/lan743x_main.o: in function `lan743x_phy_open':
 drivers/net/ethernet/microchip/lan743x_main.c:1514: undefined reference to `fixed_phy_register'

Fixes: 624864fbff92 ("net: lan743x: add fixed phy support for LAN7431 device")
