When delay reported by HW is equal to buffersize, it means the
value is wrapped so we should report as 0. So add the condition
to check this while reporting the delay from LPIB.

Some of the usecases can be marked as 'ignore_suspend' by
machine. For these on suspend we should keep audio controller
ON by saving the state and not suspending the device
For this we need to maintain a counter for these streams and be
active on suspend when such a stream is opened.

On Skylake we can support upton 4DMICs on the PDM port, so update
the PCM capabilities accordingly
Also add a new DAI for DMIC pin which can be used for getting raw
DMIC data

PCM prepare callbacks can be called multiple times. During S3
the stream registers will be reset when Controller is reset.
When stream is resumed, these stream registers needs to reconfigured.
This patch removes the check in prepare callback() if stream already
prepared, which will allow reconfiguring of stream registers and also
decouple stream when stream is resumed to route audio via DSP.

While rigourous testing of SKL drivers, we noticed underuns and
overuns and on debug realized that we need to change driver
handling of FE pipe startup and shutdown
We need to start DMA and then run pipe together and not split
these up. Similarly while stopping we should stop pipe and then
DMA in a sequence.

As a result the preinitialized dapm_path_last we had is removed
