ucm2: sof-soundwire: cs42l43: Remove outdated DisableSequence elements

cs42l43's 'Headset Microphone' and 'Microphone' devices were both used
to control mic mute LED in the past, but this was changed [1] to only
allow the built-in microphones to control the LED. Thus clean up the
DisableSequences to remove the switching off that is no longer needed.
