Subject: [PATCH] ucm2: Add UCM support for rockchip_es8316 on Pinebook Pro

Add UCM config files for Pinebook Pro's audio. The config files are
transformed and tuned from Manjaro ARM's packages:
* pinebookpro-post-install's asound.state [1]
* pinebookpro-audio's audio_jack_plugged_in.sh [2]

By the way, with these config files, the Speaker and Headphones will be
switched according to the (un)plugged state automatically.
