ASoC: cs42l56: Put the Limiter Cushion control on the limiter register

Browse source

The Limiter Cushion control writes bits 4:2 of the ALC Thresholds
register. Those bits are ALCMIN, which the ALC MIN control owns. The
datasheet puts CUSH at bits 4:2 of the Limit Thresholds Control
register, next to LMAX, which the Limiter MAX control already uses.

So setting the limiter cushion changes the ALC minimum threshold, and
the cushion itself cannot be set.

Use CS42L56_LIM_THRESHOLD_CTL.
