ASoC: sun4i-codec: Add playback only flag to quirks
Some devices only have the playback side of the codec implemented
so add a quirk to check for this. This flag is only required internally
within the codec driver, as the DAI is configured for playback only
(capture disabled) separately in the create_card() function for these
devices.
