We have eleven machine drivers who make explicit references to
gpios. Let's add the dependency.

The use of 'depends on' instead of 'select' is intentional. On one
side it could be argued that the GPIOs are required, but on the other
it might create more issues with randconfig builds. This patch sticks
with the existing direction of using 'depends' on high-level non-audio
dependencies
