Log:
  Add some more bit definitions:
  - TCO_MESSAGEx: TCO specific regs providing the ability to monitor BIOS
    bootup activity.
  - TCO_NEWCENTURY: reporting RTC year roll over.
  - TCO_NMI2SMI_EN, TCO_NMI_NOW: controlling SMIs conversion to NMIs and
    NMI trigger.
  - SMI_GBL_EN: Enabling SMI delivery for all the northbridge controller.
