Subject[PATCH] ASoC: max98357a: Fix missing include
This fixes the following compilation errors:

sound/soc/codecs/max98357a.c: In function ‘max98357a_daiops_trigger’:
sound/soc/codecs/max98357a.c:30:3: error: implicit declaration of function ‘gpiod_set_value’ [-Werror=implicit-function-declaration]
sound/soc/codecs/max98357a.c: In function ‘max98357a_codec_probe’:
sound/soc/codecs/max98357a.c:55:2: error: implicit declaration of function ‘devm_gpiod_get’ [-Werror=implicit-function-declaration]
sound/soc/codecs/max98357a.c:61:2: error: implicit declaration of function ‘gpiod_direction_output’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors

Those compilation errors can be seen for example with hppa allmodconfig.
