[PATCH -next] ASoC: hdmi-codec: fix non static symbol warnings

[Wei Yongjun <weiyj.lk@gmail.com>]

From: Wei Yongjun <weiyongjun1@huawei.com>

Fixes the following sparse warnings:

sound/soc/codecs/hdmi-codec.c:34:1: warning:
 symbol 'hdmi_device_list' was not declared. Should it be static?
sound/soc/codecs/hdmi-codec.c:80:33: warning:
 symbol 'hdmi_codec_stereo_chmaps' was not declared. Should it be static?
sound/soc/codecs/hdmi-codec.c:87:33: warning:
 symbol 'hdmi_codec_8ch_chmaps' was not declared. Should it be static?
sound/soc/codecs/hdmi-codec.c:354:6: warning:
 symbol 'hdmi_codec_eld_chmap' was not declared. Should it be static?
