ASoC: intel: sof_sdw: Support multiple groups on the same link
The current code checks the first device on a link and assumes
that all the other devices on the link will have the same endpoint
aggregation status and endpoint group ID.
Say for example a system looked like:
SDW0 - Amp 1 (Aggregated, Group 1), Mic 1 (Aggregated, Group 2)
SDW1 - Amp 2 (Aggregated, Group 1), Mic 2 (Aggregated, Group 2)
The current code would create the DAI link for the aggregated amps,
although it is worth noting that the only reason Mic 2 is not added is
the additional check that aborts processing the link when the device
changes. Then when processing the DAI link for the microphones, Mic
2 would not be added, as the check will only be done on the first
device, which would be Amp 2 and thus the wrong group, causing the
whole link to be skipped.
Move the endpoint check to be for each device rather than the first
device on each link.
