Pinebook has an ANX6345 bridge connected to the RGB666 LCD output and eDP panel input. The bridge is controlled via I2C that's connected to R_I2C bus.
There're pinebooks with 3 different panels in the wild, all 3 with different timings. Add all the compatibles to panel node and hope that we can get correct timings from EDID. If reading EDID fails it's up to firmware to fixup compatible string.
Enable all this hardware in device tree.
