igb: Remove GS40G specific defines/functions

The I210 internal PHY can be accessed just as well with the access
functions shared by 82580, I350, and I354 devices. A side effect of
relying on the common functions, is that I210 cable length support
is folded back into the common case which effectively reverts the
following commit:
