ALSA: cs35l41: Add shared boost feature

Browse source

Shared boost allows two amplifiers to share a single boost circuit by
communicating on the MDSYNC bus.
The passive amplifier does not control the boost and receives data from
the active amplifier.

Shared Boost is not supported in HDA Systems.
Based on David Rhodes shared boost patches.
