Smatch warns that we dereferenced substream before check, so fix
this by initializing ebus after the check

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.

in_pin and out_pin list for a module has the information about
the module that are bound together. So we can directly look at
pin information of module for binding and unbind.
As a result the preinitialized dapm_path_last we had is removed
and code and memory optimzed.

Return value from skl_tplg_be_update_params() is ignored. But if the
blob is null then the hw_params needs to return error.
This patch fixes the issue by not ignoring return value from
skl_tplg_be_update_params().

pm_runtime_get_sync() will return a negative value in case of
error and can return postive value for success. The return check
for pm_runtime_get_sync() must be less than 0, so fix it

Initialize and creates DSP controls if processing pipe capability
is supported by HW. Updates the dma_id, hw_params to module param
to be used when DSP module has to be configured.

We need to create CPU DAI for each endpoint instance. For this we
should have one DMIC DAI, one HDA DAI and SSP DAI. Thus, DMIC23,
HDA-SPK/AMIC was not required so this patch removes them

Decoupled mode is where audio link is broken to frontend HDA and backend
(hda/i2s/dmic/hdmi) links. This patch adds support for decoupled mode and
then adds dais, dai ops for be/fe cpu dais and interrupt handler change to
support decoupled mode
