e1000: rework polarity, NVM, eeprom code and fixes.

Several minor issues exist in the low-level device handling code of
e1000. The NVM and EEPROM writing/reading code was updated which fixes
unneeded delays, adds proper eeprom aqcuiring steps and handle shadow
ram and flash access. Minor cosmetic adjustments to the polarity code
adding symbols. PHY reset code mistakenly distinguished between MAC
types instead of PHY types, and was fixes.
