AMD SB7XX gameport

A tool that controls the gameport on the SB700 and later southbridges found
on motherboards with AMD chipsets. The port seems to be enabled on some boards
even though it's not physically present and clashes with soundcard ports.

Tested on an ASRock A780GXH/128M under Arch linux. The gameport was on an
Ultron QuadroSound (C-Media CMI8738). Requires the pciaccess library.

Usage:

sb7xxgameport status returns the current state of the gameport,
on, enables and off disables it.

Note about the CMI8738. The C-Media driver doesn't enable the gameport
by default. To enable it use the joysitck_port module option.
Probably the easiest way is to add a .conf file with the
contents options snd-cmipci joystick_port=1 to /etc/modprobe.d.
