Log Message:
gpio(4) support for Intel ICH southbridges.

Tested on Intel SS4200-E (ICH7), and Acorp 6A815EPD (ICH2) motherboards,
on amd64 and i386 ports respectively.

It should be noted that the majority of boards with ICH chips do not
expose the GPIO pins for off-board use.  For instance, aside from the
three exposed-on-a-header pins on the 6A815EPD, another pin is also
used to control write protect on the FWH.  The SS4200 exposes the GPIO
on a header that connects to the 10 LEDs on the front panel, as well
as a tact switch on the back panel.
