To avoid power leakage, it is recommended to replace the default pinctrl
state with dynamic pinctrl since certain audio pinmux functions can
remain in a HIGH state even when audio is disabled. Linking pinctrl with
DAPM using SND_SOC_DAPM_PINCTRL will ensure that audio pins remain in
GPIO mode by default and only switch to an audio function when necessary.
