Update the driver to use SND_SOC_DAPM_AIF_IN instead of
SND_SOC_DAPM_DAC.
Rename the interface's widgets to be more precise on which slot
the interface is connected.

An unwanted space is present in an audio widget's name on the dapm
routing. It causes an error on the recognition of this widget (error:
("no dapm match for AIF1 Slot 0 Right").

Remove the space fixes it.

Update the driver to use the new SOC_DAPM_DOUBLE definition
on the digital DAC mixer.
Update the names accordingly as, when they are shared, the
controls are not prefixed with the widget's name anymore.

The "HP" widget is already present and take part to
the analog part (sun8i-codec-analog).

Remove it from the digital part as it is unnecessary.

Add the sun8i audio codec which handles the digital register of
A33 codec.
The driver handles only the basic playback from the DAC to headphones.
All other features (microphone, capture, etc) will be added later.
