9fe7c416e6 intpm: add support for SB800
This code should be able to support later AMD chipsets as well, but that
hasn't been tested.

SB800 supports accessing several different SMBus buses using the same
set of constrol registeirs plus special PMIO registers that control which
bus is selected.  This could be exposed to consumers as several smb devices
each talking to its bus.  This feature is not implemented yet.
