Subject: [PATCH v2 -next] ASoC: wm_adsp: Make some variables static

From: YueHaibing <yuehaibing@...wei.com>

Fix sparse warnings:

sound/soc/codecs/wm_adsp.c:309:20: warning: symbol 'wm_adsp1_ops' was not declared. Should it be static?
sound/soc/codecs/wm_adsp.c:310:20: warning: symbol 'wm_adsp2_ops' was not declared. Should it be static?
sound/soc/codecs/wm_adsp.c:311:20: warning: symbol 'wm_halo_ops' was not declared. Should it be static?
