Subject: [PATCH] ASoC: sti-uniperf: Use default pcm_config instead

The sti-uniperf pcm_config is the same as the default pcm_config.

Since commit 43556516fffe ("ASoC: soc-generic-dmaengine-pcm:
Use default config when none is given"), passing a NULL pointer
could let this driver use the default config.
