PINE64 - HDMI CEC

I posted here what needs to be done to run this experiment on existing Pine A64 devices: https://github.com/ayufan-pine64/android-hdmi-cec-sunxi

HDMI Standby doesn't work correctly.

Other then that everything else works almost fine with recent fixes to linux driver.

I have working Android build with HDMI CEC.

As a side thing I added 4K output to Android builds (fortunately only 4K/30fps)

Oh. I think that I'm almost there to make HDMI CEC driver more reliable. I just need to find a way to detect when there's no data on the line.
