Subject: [PATCH -next] ASoC: hdmi-codec: Make symbol 'hdmi_codec_controls' static

The sparse tool complains as follows:

sound/soc/codecs/hdmi-codec.c:750:25: warning:
 symbol 'hdmi_codec_controls' was not declared. Should it be static?

This symbol is not used outside of hdmi-codec.c, so marks it static.

Fixes: 366b45b97448 ("ASoC: hdmi-codec: Rework to support more controls")
