* Give symbolic names to the CFG bits in the EEPROM.

Browse Source 
* Get CFG_M64ADDR, CFG_T64ADDR, and CFG_DATA64_EN from the EEPROM.
  Note, we still disable CFG_M64ADDR and CFG_T64ADDR later (XXX need
  PCI bus capability flags for these).
* Print a message if we're in a 64-bit slot and 64-bit data is
  disabled in the EEPROM.  Make sure CFG_DATA64_EN is disabled if
  we're not in a 64-bit slot.
