[PATCH] ASoC: amd: fix Kconfig warning for Renoir

[Randy Dunlap]

From: Randy Dunlap <rdunlap at infradead.org>

SND_SOC_DMIC depends on GPIOLIB so this driver should also depend on
GPIOLIB to make kconfig happy.

WARNING: unmet direct dependencies detected for SND_SOC_DMIC
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && GPIOLIB [=n]
  Selected by [y]:
  - SND_SOC_AMD_RENOIR_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_AMD_RENOIR [=y]

Fixes: 1d3776669323 ("ASoC: amd: enable build for RN machine driver")

There are no object file build errors. I suppose that gpiolib stubs
take care of that. Maybe some other patch would be more appropriate.
