A dsp path and the modules in the path can support various pcm
configurations. The list of supported pcm configurations from topology
manifest would be stored and later selected runtime based on the hw
pcm params. For legacy, module data is filled in the 0th index of
resource and interface table.
To accommodate both models, change the relevant structures and populate
them by parsing newly defined tokens. This change is backward compatible
with the existing model where driver computes the resources required by
each dsp module.

Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
Signed-off-by: Mark Brown <broonie@kernel.org>
Module at the end of DSP pipeline that needs to be connected to a module
in another pipeline are represented as a PGA(leaf node) and in PGA event
handler these modules are bound/unbounded. Modules other than PGA leaf
can be connected directly or via switch to a module in another pipeline.
Example: reference path.
To support the deferred DSP module bind, following changes are done:
o When the path is enabled, the destination module that needs to be
bound may not be initialized. If the module is not initialized, add
these modules in a deferred bind list.
o When the destination module is initialized, check for these modules
in deferred bind list. If found, bind them.
o When the destination module is deleted, Unbind the modules.
o When the source module is deleted, remove the entry from the deferred
bind list.

As per hardware recommendation, for every capture stream completion
following operations need to be done in order to reflect the actual
data that is received in position buffer.
1. Wait for 20us before reading the DMA position in buffer once the
interrupt is generated for stream completion.
2. Read any of the register to flush the DMA position value. This is
dummy read operation.

In system suspend, the firmware pipelines will be deleted and there
is no need to save the pipeline context. Driver will save the DPIB and
LPIB pointers in suspend.
In system resume, the firmware pipelines will be created again and the
RD/RW pointers in the Firmware buffer points to the base address. So
need to fetch the non-played data again to firmware buffer. LPIB
indicates the HW rendered position.
Instead of setting DPIB as resume point, set it to LPIB to restore from
the HW render position so that DMA would fetch the non-played data one
more time.

DPIB is read currently from a buffer position in memory (indicated by
the registers DPIB[U|L]BASE).Driver reads the position buffer on BDL
completion interrupts to report the DMA position. But the BDL completion
interrupt only indicates the last DMA transfer of the buffer is
completed at the Intel HD Audio subsystem boundary. The periodic DMA
Position-in-Buffer writes may be scheduled at the same time or later
than the MSI and does not guarantee to reflect the position of the last
buffer that was transferred.
Whereas DPIB register in HDA space(vendor specific register indicated by
SDxDPIB) reflects the actual data that is transferred. Hence update the
position based on DPIB for playback.
