o Don't access VPD even if hardware advertised the capability.

  It seems that some revision of controller hang while accessing
  the VPD. Because VPD access routine are unused, nuke it.
o Let TWSI reload EEPROM if VPD capability is detected. Reloading
  EEPROM will also set ethernet address so age(4) now reads AGE_PAR0
  and AGE_PAR1 register to get ethernet address. This removes a lot
  of hack and enhance readability a lot.
o Double PHY reset timeout as it takes more time to take PHY out of
  power-saving state.
o Explicitly check power-saving state by checking undocumented PHY
  registers. If link is not up, poke undocumented registers to take
  PHY out of power-saving state. This is the same way what Linux
  does. On resume, make sure to wake up PHY.
o Don't rely on auto-clearing feature of master reset bit, just wait
  1ms and check idle status of MAC.
o Add PCI device revision information in bootverbose mode.
This should fix occasional controller hang in device attach phase.
