Add support for the Rockchip rk817 audio codec integrated into the rk817 PMIC. This is based on the sources provided by Rockchip from their BSP kernel. Would someone advise what they think the best way to get the widgets set up properly would be? I'm still new to this and I don't fully understand all the macros (the alsa-project.org documentation only gets me so far).
TODO: Get HP detect working, see if I can improve the audio path widgets.
