ASoC: omap: rx51: Add earphone support
Earphone in Nokia RX-51/N900 is connected to left HP output of B part of the TLV320AIC34 dual codec. In RX-51 the codec A is used as a traditional codec and the codec B as an auxiliary device. Audio from codec A goes via the codec B to earphone: MONO_LOUT of A -> LINE2R of B (B interconnects) -> HPLOUT of B -> Earphone. Take earphone into use by utilizing the recent ASoC auxiliary and cross-device support.
