All revisions of the PinePhone have an SGM3140 LED flash. The gpios were
swapped on v1.0 of the board but this was fixed in later revisions.

The nodes should be ordered by node-name here

The label will be used for connecting the flash to the rear camera (which 
hasn't been upstreamed yet) using:

    flash-leds = <&sgm3140_flash>;

Hope that clears it up.
