DaVinci: DM365: Voice Codec support for the DM365 EVM

The DM365 EVM has two codecs: the Audio Codec (AIC3x) and the Voice Codec,
the idea is to have both enabled in the same kernel simultaneously. However,
the current soc-core doesn't support simultaneous codecs, once that
support will have added, a patch will be posted to enable both codecs in
the DM365 EVM.
