codecs/es8316: Fix mono speaker settings from previous boot getting applied

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.
