lan743x: Remove MAC Reset from initialization 



[ Upstream commit e0e587878f538c9e3400219b6c516b8199dc2042 ]

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.
