avg fbe075bad3 intpm: add support for smbus controller found in AMD SB700
According to the specifications AMD/ATI SMBus controller is very
similar to SMBus controller found in PIIX4.
Some notable differences:
 o different bit for enabling/signalling regular interrupt mode
 o in practice seems to support only polling mode
Thus, intpm driver is modified to support polling-only mode
and to recognize SB700 PCI ID and differences.

Tested on:	SB700 and PIIX4E platforms

X-Perhaps-ToDo:	rename the driver to reflect its function
		and supported hardware
