ASoC: ab8500: Remove the nonfunctional sidetone apply control

Browse source

After the coefficient controls were removed, writing "Apply FIR"
programs 128 zero coefficients and reports that the sidetone filter is
configured. The associated ANC configuration DAPM pins are also now
unreachable dead infrastructure.

Remove the misleading status/apply control, its private state, and the
obsolete configuration-only DAPM pins. Keep the direct sidetone reset
and remaining hardware controls.
