gpio_cs5535: disable AUX on output
The AMD CS5535/CS5536 GPIO has two alternate output modes: AUX-1 and AUX-2.
When either AUX is enabled, the cs5535_gpio driver cannot control the
output.
Some BIOS code for the Geode processor enables AUX-1 for GPIO-1, which
configures it as the PC BEEP output.
This patch will disable AUX-1 and AUX-2 when the user enables output.
