Bug description:
[Impact]
Mic mute LED doesn't work on Intel-based HP laptops.
[Fix]
Due to recent change on how kernel creates sound LEDs, there are two captures
are registered, one from SoF and one from HDA. The SoF one is the "real"
capture system uses.
Since physical LED only gets light up when _all_ captures are muted,
detach the HDA one so micmute LED only need to consider SoF capture's
mute status.
[Test]
The mic mute LED works again on DMIC laptops.
The legacy HDA systems are unaffected.
[Where problems could occur]
Theoretically the system may have more than two internal captures registered,
then disabling one will not be enough.
