arm64: dts: qcom: x1e80100-crd: Fix backlight
The backlight does not work correctly with the current display panel
configuration: It works after boot, but once the display gets disabled it
is not possible to get it back on. It turns out that the ATNA45AF01 panel
needs exactly the same non-standard power sequence as implemented by the
panel-samsung-atna33xc20 driver for sc7180-trogdor-homestar.
Switch the panel in the DT to the new compatible and make two more changes
to make it work correctly:
1. Add the missing GPIO for the panel EL_ON3 line (EDP_BL_EN on CRD and
enable-gpios in the DT).
2. Drop the regulator-always-on for the panel regulator. The panel does
not seem to power off properly if the regulator stays on.
