Support for clock recovery in compress driver.
Userspace app can issue clock recovery command with a positive value
to advance the clock or a negative value to delay the clock.

Update compress driver to support configuration of DSP render
window. Render window is used by DSP to take rendering decision.
i.e whether input frame should be rendered, dropped or repeated.

Update compress driver to support configuration of DSP clock
recovery mode. Supported modes are auto and none. In auto mode
DSP does clock recovery based on avtimer and device drift otherwise
it ignores drift.

Populate the sample rate, encode option in wma config params.
WMA V9 and WMA Pro tunnel-mode supports are added to compressed
driver. It allows user-space application to decode WMA V9 and
WMA Pro audio stream through QDSP6.
Codec specific metadata is sent only for first stream in gapless
playback. This causes incorrect configuration to be set for second
stream and distortions are observed due to framedrops in adsp.
Add support to send codec specific format during start of
next stream in gapless.
Add bit rate to wma codec data structure as it can vary between
streams in gapless.

Add audio backend to hwdep interface. This is to provide
ioctl interface to communicate to routing driver.
Currently codec driver uses request_firmware to get calibration data
but as this firmware file is also written by userspace process after
bootup, it is not recommended to use request_firmware. ALSA core
provides mechanism to get hardware dependent data using hwdep nodes.
Codec will use aforementioned nodes to get calibration data from
userspace.
This commit adds hwdep interface for codec calibration.

Currently ASoC core creates a static route b/w
playback/capture widgets of cpu and codec dai
if they are part of the same dai-link. However
this will cause codec path to get powered up
followed by the backend dai start during device
switch use-case where the front-end is not closed,
leading to audio playback failure if either bit-width
or sample rate is different.

ASoC: Fix freed memory access of pcm stream kctl
Consider sound card instantiate fails due to
audrx init failure. In such case, all dais/ctls
are de-registered and freed. But as part of it,
access to unregistered ctls for pcm_chmap and similar
controls result in crash. Ctls are freed at disconnection
but the disconnect is called only when it was registered.
