ravb: Factorise ravb_emac_init function
The E-MAC IP on the R-Car AVB module has different initialization
parameters for RX frame size, duplex settings, different offset
for transfer speed setting and has magic packet detection support
compared to E-MAC on RZ/G2L Gigabit Ethernet module. Factorise
the ravb_emac_init function to support the later SoC.
