[PATCH 11/11] ASoC: SOF: ipc4-topology: Search only pin 0 formats

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

Base config only contains the input/output audio formats for pin 0. So
match only the pin 0 formats during runtime format selection.
