Pointer member variables in snd_codec params break bit alignment and
causes data corruption. By changing these pointers to fixed size
array variables, the bit alignment is rectified. The size has been
set to max possible size. Also, remove params which are not required
anymore.

Kernel 3.10 has cpu dai widgets in the list of card
widgets in addition to platform and codec widgets.
This is causing a delay in device switch because
cpu dai widgets increase the number of widgets to be
processed for bias changes by a factor of five, however
they are not required to be processed.
Skip processing of cpu dai widgets to keep
the device switch latency at same level as in kernel 3.4.

Incase of A2DP usecase using proxy driver, appl_ptr has
boundary value as 0x60000000 frames in sw_params for stereo(2 channels).
When this value crosses 0x40000000, then userspace calculating
appl_ptr at bytes results in crossing 32-bit value 0x100000000,
and points to 0x0 offset which can result in crash or pop.
To avoid above scenario, set the sw_params appl_ptr boundary value
within 0x40000000. Added proper check at sw_params update
to set this value correctly within 32-bit boundary(frames).

Be from the DSP, in mmap mode for the scenario Hardware pointer
Is same as application pointer implies application has not filled the
Buffer to be send to DSP, and platform driver has to break and restart
The de queue process when the application has sufficient buffers.
When hardware pointer is same as application pointer it is an under run
Scenario where the ALSA framework has to trigger the under run and in HAL
The session has to re-prepare and re-triggered. based on the stop
Threshold, but in our system the stop threshold is INT_MAX which
Indicates that under run is not triggered in practical cases.
We have a brodcast usecase in which the mentioned under run case
Is hit mulitple times, and every time re-prepare and re-trigger will be
Expensive
Update the ASoC core framework to restart de queue process stopped
By platform Driver when the under run is hit, based on the available
Buffer and render flag, so the System will recover from the hang state.
To restart de queue process the ASoC core will be calling the restart
Callback registered by platform driver and this callback will be running in
Atomic context.
