ASoC: WCD9304: Add the compander support to wcd9304

The compander system is intended to increase the dynamic
range of an input signal. But for the wcd9304 codec,
this feature is to use companding in a novel way in the DAC
converter path to increase the signal noise ratio.
The change is to add the compander support to wcd9304
codec. The dynamic compander enable/disable during stream
playback is not supported.

msm: mdm: change where ssr_count is decremented

In fusion targets with more than one external modem, where
the modems are restarted together, ssr_count keeps track of
how many modems are still left to be completely restarted so
that any new SSR requests would be rejected until all modems
are restarted. Ssr_count should be decremented when the SSR
module sends the SUBSYS_AFTER_POWERUP notification instead of
during the powerup callback in order to be in sync with the
state of the SSR module.
