ASoC: dapm: use component prefix when checking widget names

Browse Source 
commit ae4fc532244b3bb4d86c397418d980b0c6be1dfd upstream.

On a TigerLake SoundWire platform, we see these warnings:

[   27.360086] rt5682 sdw:0:25d:5682:0: ASoC: DAPM unknown pin MICBIAS
[   27.360092] rt5682 sdw:0:25d:5682:0: ASoC: DAPM unknown pin Vref2

This is root-caused to the addition of a component prefix in the
machine driver. The tests in soc-dapm should account for a prefix
instead of reporting an invalid issue.
