MLK-21627: ASoC: imx-pcm-dma-v2: add debugfs_prefix for platform
There is warning log after switching to component in driver:
[ 3.321645] fsl-sai
30030000.sai: ASoC: Failed to create component debugfs directory
The reason is there is two component attached with one device,
the components' name are same, then creating debugfs for second
component failed.
This patch is to add debugfs_prefix for platform component to fix
the warning issue.
