ASoC: Intel: boards: remove explicit dependency on GPIOLIB when DMIC is used"

This patch reverts commit 4262ddc2ad63 ("ASoC: Intel: boards: add
explicit dependency on GPIOLIB when DMIC is used") and all follow-up
additions of this dependency.

Now that the DMIC does not depend on GPIOLIB we can simplify again.
