lan743x: Remove MAC Reset from initialization



The MAC Reset was noticed to erase important EEPROM settings.
It is also unnecessary since a chip wide reset was done earlier
in initialization, and that reset preserves EEPROM settings.

There for this patch removes the unnecessary MAC specific reset.
