[SRU][B/OEM-B/D/OEM-OSP1/E/unstable][PATCH 0/2] External microphone can't work on some dell machines with the codec alc256 or alc236

BugLink: https://bugs.launchpad.net/bugs/1853791

[Impact]
The external microphone can't work on some dell machines with the
codec alc256 or alc236

[Fix]
Need to apply the ALC255_FIXUP_DELL1_MIC_NO_PRESENCE, instead of
adding a new pintbl in the quirk table, we use fallback table this
time.

[Test Case]
tested the kernel with these patches, the external mic worked well.

[Regression Risk]
Low, just make the quirk applying more generic.
