The new mt6797-afe driver uses some functions in a common file, which
works for a built-in driver but fails for a loadable module:
ERROR: "mtk_afe_pcm_free" [sound/soc/mediatek/mt6797/snd-soc-mt6797-afe.ko] undefined!
ERROR: "mtk_afe_add_sub_dai_control" [sound/soc/mediatek/mt6797/snd-soc-mt6797-afe.ko] undefined!

ERROR: "mtk_afe_pcm_ops" [sound/soc/mediatek/mt6797/snd-soc-mt6797-afe.ko] undefined!
This exports the five symbols above for modules.

In MediaTek SoC chip we have multiple DAI,
such as I2S, ADDA, PCM, etc.
Organize each DAI in to one sub dai,
with its dai driver, controls, widgets, routes.
add mtk_afe_combine_sub_dai() to combine
dai driver from each DAI.
add mtk_afe_add_sub_dai_control() to register
the control, widget, routes to component.

We get 2 warnings about global functions without a declaration
in the ASoC mediatek module when building with W=1:
sound/soc/mediatek/common/mtk-afe-fe-dai.c:26:5: warning: no previous prototype for 'mtk_regmap_update_bits' [-Wmissing-prototypes]
int mtk_regmap_update_bits(struct regmap *map, int reg, unsigned int mask,
^
sound/soc/mediatek/common/mtk-afe-fe-dai.c:34:5: warning: no previous prototype for 'mtk_regmap_write' [-Wmissing-prototypes]
int mtk_regmap_write(struct regmap *map, int reg, unsigned int val)
In fact, all of those functions are only used in the file in which
they are declared and don't need a declaration, but can be made static.
so this patch marks it 'static'.
