ASoC: atmel-pdmic: mark symbols static where possible
We get 1 warning about global functions without a declaration in the ASoC atmel-pdmic driver when building with W=1: sound/soc/atmel/atmel-pdmic.c:286:5: warning: no previous prototype for 'pdmic_get_mic_volsw' [-Wmissing-prototypes] In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. so this patch marks it 'static'.
