This adds the necessary registers and audio routes to play audio using the Earpiece, that's supported on the A64.

So, first of all: This is my first audio patch and I hope I didn't make too many mistakes :) , especially with the routes at the bottom of the patch.
What I'm really unsure about, is how the enable & mute registers should be handled. Should I put both registers into a SOC_DOUBLE("Earpiece Playback Switch",...)?
What we normally have with sunxi is the "Enable" switches typically control whether a given function is active or not. With the earpiece output, it controls the amplifier for the output. This should be modeled as a separate DAPM widget, without a control, and let the framework deal with it.
The mute controls the signal, so you can just keep as a control.

I suggest dropping "Analog" to match what other controls, such as the Headphone Source" control, uses.
