device-pine64-pinephone/pinetab: increase maximum volume headphone jack
The audio volume of headphones is quite low on the PinePhone and PineTab with pmOS.
The reason is the low volume in the ALSA UCM config: 40%
instead of 100%
like on other distros.
Increasing the volume in the UCM config make headphones much more usable on the PinePhone and PineTab.
