Subject: [PATCH 2/2] ASoC: sunxi: sun4i-codec: set debugfs_prefix for CPU DAI component

At present, succesfull probing of H3 Codec results in an error

    debugfs: Directory '1c22c00.codec' with parent 'H3 Audio Codec' already present!

This is caused by a directory name conflict between codec
components. Fix it by setting debugfs_prefix for the CPU DAI
component.
