[PATCH net-next 5/5] net: fec: remove duplicate macros of the BD status

[Wei Fang <wei.fang@nxp.com>]

There are two sets of macros used to define the status bits of TX and RX
BDs, one is the BD_SC_xx macros, the other one is the BD_ENET_xx macros.
For the BD_SC_xx macros, only BD_SC_WRAP is used in the driver. But the
BD_ENET_xx macros are more widely used in the driver, and they define
more bits of the BD status. Therefore, let us remove the BD_SC_xx macros
from now on.
