It is possible that codec hardware can be reset in case of subsystem
restart scenarios. It is required to reset the codec DSP as well in
such cases to make sure the DSP is in usable state after the codec
hardware is reset. Change adds support to handle codec down and up
events and perform the necessary reset on codec DSP.

The wdsp_intr_handler is not really processing interrupts in interrupt
context, rather assumes that the caller is not in interrupt context and
performs calls that may sleep. Rename the function in order to avoid
confusion. Interrupt handlers can still call this function as long as
they are in threaded interrupt context and are okay to sleep.

One time initializations like regmap and debugfs init are currently
done in the init function. But, in case of subsystem restart, the
driver can get de-initialized and then initialized again. This causes
the debugfs and regmap entries to get removed and added again during
subsystem restart cases. Avoid this by moving all the one time
initialization of the driver to component bind.

Lowlatency playback is failed to start when FM is going on because
of wrong channel count in backend DAI. Channels are overwritten because
of afe loopback port mixer caching variable(port_sessions) overflow.
Fix this issue by creating an array to track all the loopback

During image download, the status is set after post download events
are broadcasted. This could possibly lead to race condition if other
drivers requested to boot the dsp before the status was set. Change
makes sure the wdsp status is set prior to broadcasting post download

Currently, the clock request is performed during init and the clock
is kept on assuming that there will be code download event followed
by init. This assumption may not always be true and might cause the
clock to be enabled when it is really not needed. Change fixes clock
disable such that clock is disabled right after init and re-enabled
again if code download event is raised.
