This patch contains some significant updates to the i82801gx component and will
be required for a series of later patches. Roughly it contains:

* fixed SMBus driver (was not compiled in before)
* fixed S-ATA/P-ATA combination
* Added warnings to drivers being called with a NULL dev->chip_info 
* Set subsystem ids for those boards that have none specified in Options.lb
* Fix license headers. The code was originally released under GPL v2 but
  some files sneaked in with a v2 or later header.
* some attempts to fix azalia/Intel HDA.. not working yet
* clean up and fix pci bridge handling code
* Add Config based GPI handling to LPC driver
* Add HPET enable function
* Enable clock gating where appropriate
* first attempt at USB debug console support (not working yet)
* Add required options to kontron board
* many other minor changes

-PMBASE		0x1000 (128 bytes)

-HWMON		0xa00 (??)

-
-NOTE: Coreboot sets the SMBASE to 0xf00 in auto.c. But it gets relocated 
-in stage2 because its a "normal BAR" (to 0x2080 in one case here). 
-
-This is not unhealthy but at least confusing. We should provide a method to
-nail down certain resources for stage2. 
-
-For a list of static I/O space allocation look at 6.3.1 of the ICH7 Family
