In soundwire controller, bank switch happen twice
for a playback session with stereo speakers. Ensure
the setting of div2 applied to inactive bank before
bank switch occurs to avoid impact based on bank chosen.

When stereo playback start and temperature read
initiated at same time, one of speaker PA bits are
not set in particular race scenario. Handle the
broadcast check in soundwire framework to ensure
broadcast is disabled only when respective gr_sid
slave calls swr_remove_from_group.

When temperature on a single wsa881x device is being read,
then soundwire master wakes up both wsa881x devices but
regcache_sync is happening only for one wsa881x device on
which the temperature is being read. This results in
audio playback mute after temperature read. Fix the
regcache sync during temperature read and playback usecase.

In SDM660 WSA speaker using MSM over soundwire version,
observe high cold start latency. As interrupt is disabled,
broadcast ack is not received which results in 200ms higher
latency. Reduce latency impact by blocking only for 10ms
for MSM over soundwire version.

Soundwire does not have usecase with smart boost disabled. This
results in data port collisions when smart boost port is disabled
from mixer control which results in noise during audio playback.
