When codecs/es8316/MonoSpeaker.conf's EnableSeq was run last before shutdown the 'Playback Polarity' and 'DAC Mono Mix Switch' controls for Mono Speaker output get saved and restored on the next boot.

These settings are undone by the MonoSpeaker DisableSeq, but that never runs when an updated kernel switches from the default "cfg-spk:1" in components to "cfg-spk:2" for devices which do actually have 2 speakers, which causes the ucm profile to use codecs/es8316/Speaker.conf instead.

Set the 'Playback Polarity' and 'DAC Mono Mix Switch' controls to their defaults in codecs/es8316/EnableSeq.conf to avoid them getting stuck in Mono mix mode in this scenario.
