Add ALSA UCM support for Pinebook Pro's audio

[Jian-Hong Pan]

Hi,

I prepared the pull request "ucm2: Add UCM support for rockchip_es8316 on
Pinebook Pro" [1] to enable Pinebook Pro's audio generically.
Also, the corresponding validator pull request "ucm-validator: Upload
rockchip_es8316's dummy json and alsa-info" [2].

The original information comes from Manjaro ARM's
pinebookpro-post-install's asound.state [3] and pinebookpro-audio's
audio_jack_plugged_in.sh [4].

To make it available on most distros, I transfer the asound.state and the
shell script into ALSA UCM conf.

It will be appreciated if someone can review the pull requests and give
some feedback.
