[PATCH] ASoC: amd: fix unmet dependency on GPIOLIB for SND_SOC_DMIC

[Julian Braha]

When SND_SOC_AMD_YC_MACH is selected,
and GPIOLIB is not selected,
Kbuild gives the following warning:

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_YC_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_AMD_ACP6x [=y]

This is because SND_SOC_AMD_YC_MACH selects SND_SOC_DMIC,
without selecting or depending on GPIOLIB, despite
SND_SOC_DMIC depending on GPIOLIB.

This unmet dependency bug was detected by Kismet,
a static analysis tool for Kconfig. Please advise
if this is not the appropriate solution.
