ASoC: sunxi: Add support for A23/A33/H3 codec's analog path controls



The internal codec on A23/A33/H3 is split into 2 parts. The
analog path controls are routed through an embedded custom register
bus accessed through the PRCM block.

The SoCs share a common set of inputs, outputs, and audio paths.
The following table lists the differences.

    ----------------------------------------
    | Feature \ SoC |  A23  |  A33  |  H3  |
    ----------------------------------------
    | Headphone     |   v   |   v   |      |
    ----------------------------------------
    | Line Out      |       |       |  v   |
    ----------------------------------------
    | Phone In/Out  |   v   |   v   |      |
    ----------------------------------------

Add an ASoC component driver for it. This should be tied to the codec
audio card as an auxiliary device. This patch adds the commont paths
and controls, and variant specific headphone out and line out.
