ASoC: fsl_asrc_dma: fix duplicate debugfs directory error

Browse Source 
This driver registers a component for asrc. This is also used together
with easrc, both attached using the device name as component name.
Eventually debugfs directories with identical name are created in
soc_init_component_debugfs(), leading to error message:
  debugfs: '30c90000.easrc' already exists in 'tqm-tlv320aic32'
Fix this by adding the debugfs_prefix.
