ravb: Update ravb_emac_init_gbeth()
This patch enables Receive/Transmit port of TOE and removes
the setting of promiscuous bit from EMAC configuration mode register.
This patch also update EMAC configuration mode comment from
"PAUSE prohibition" to "EMAC Mode: PAUSE prohibition; Duplex; TX;
RX; CRC Pass Through".
