ixgbe: update to latest common code module

This is a massive update that includes infrastructure for further patches
where we will add support for more phy types and eeprom types.

This code is shared as much as possible with other drivers, so the code may
seem a little obtuse at times but wherever possible we keep to the linux
style and methods.
