jme: Added half-duplex mode and IPv6 RSS fix
1. Set bit 5 of GPREG1 to 1 to enable hardware workaround for half-duplex
mode. Which the MAC processor generates CRS/COL by itself instead of
receive it from PHY processor.
2. Set bit 6 of GPREG1 to 1 to enable hardware workaround that masks the
MAC processor working right while calculating IPv6 RSS in 10/100
mode.
3. Group the workaround codes all together.
