22e766146a ASoC: mediatek: mark symbols static where possible
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'.

8d6f88ce96 ASoC: mediatek: Use current HW pointer for pointer callback
Previously we recorded "last interrupt position" and used it in
pointer callback. This is not correct implementation, and it causes
underruns when user space monitors buffer level to decide when to
send next data chunk in low latency application.

Remove position recording in IRQ handler and also hw_ptr in
struct mtk_afe_memif used to record that, and let pointer callback
reports current HW pointer instead.

e4fba9b5be ASoC: mediatek: Increase periods_min in capture
In capture, there is chance that hw_ptr reported at IRQ is
a little smaller than period_size due to internal AFE buffer.
In the case of ping-pong buffer:

|xxxxxxxxxxxxxxxxxxxxxxxxxxxx--|-----------------------------|
                            hw_ptr < period_size

This available buffer will not be read since its size is smaller than
avail_min (which is period_size by default), and read thread continues
to sleep. If the next hw_ptr is just a little larger than buffer_size,
overrun occurs. One more period can hold the possible unread buffer.

0643558f85 ASoC: mediatek: Remove AIF widgets for backend DAIs
DAPM core already creates widgets for DAIs. It is not necessary
to declare them by SND_SOC_DAPM_AIF_IN/SND_SOC_DAPM_AIF_OUT.
Furthermore, original codes use backend DAI's stream name to be the AIF
widget name. It causes the same widget to be created twice, and after
commit 92fa124267 ("ASoC: dapm: Add new widgets to the end of the
widget list") the first created widget (by snd_soc_dapm_new_controls)
is used, not the 2nd created one (by snd_soc_dapm_new_dai_widgets),
so audio path is broken.
