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
