ASoC: fsl_easrc: fix duplicate debugfs directory error

This driver registers two components: asrc and 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.
