ASoC: mediatek: mt8186: fix AUD_PAD_TOP register and offset

AUD_PAD_TOP widget's correct register is AFE_AUD_PAD_TOP , and not zero.
Having a zero as register, it would mean that the `snd_soc_dapm_new_widgets`
would try to read the register at offset zero when trying to get the power
status of this widget, which is incorrect.

To avoid spamming the console, move these messages to the debug level.

ASoC: mediatek: mt8186: fix DMIC record noise

When the first DMIC recording is power down, mtkaif_dmic will be reset.
This will cause configuration error in the second DMIC recording. So do
not reset mtkaif_dmic except in "MTKAIF_DMIC Switch" kcontrol.

ASoC: mediatek: mt8186: remove unnecessary judgments

The afe_priv->dai_priv[] is allocated when platform driver probe(), if it
failed, the ASoC platform driver probe() will return fail first.
Therefore, this is excessive judgment, and the condition will never be
established.

ASoC: mediatek: mt8186: set the correct string to strncmp()

Fix Smatch static checker warning. strncmp() here only needs to compare
the first seven bytes, so in order to make the code more clear, only the
