Peter Ujfalusi e298bf6f55 ASoC: SOF: Intel: Read the LLP via the associated Link DMA channel 
[ Upstream commit aaab61de1f ]

It is allowed to mix Link and Host DMA channels in a way that their index
is different. In this case we would read the LLP from a channel which is
not used or used for other operation.

Such case can be reproduced on cAVS2.5 or ACE1 platforms with soundwire
configuration:
playback to SDW would take Host channel 0 (stream_tag 1) and no Link DMA
used
Second playback to HDMI (HDA) would use Host channel 1 (stream_tag 2) and
Link channel 0 (stream_tag 1).

In this case reading the LLP from channel 2 is incorrect as that is not the
Link channel used for the HDMI playback.

To correct this, we should look up the BE and get the channel used on the
Link side.
