DACREF power source can come from external 1.8V or codec internal 1.8V. This patch adds the option to enable the internal DACREF power source.

- Select codec internal 1.8V as DACREF source optionally.
Why is this not done using the regulator API - don't we need to ensure that the external DACREF is enabled if it's there? I don't think we need to model the internal reference as a regulator (we can just set the registers up in that case) but if it's off device I'd expect to be making sure that it's turned on.
