t4240qds/eth: fixup ethernet for t4240qds

1, Implemented board_ft_fman_fixup_port() to fix port for kernel.
2, Implemented fdt_fixup_board_enet() to fix node status of different
   slots and interfaces.
3, Adding detection of slot present for XGMII interface.
4, There is no PHY for XFI, so removed related phy address settings.
