The Samsung ATNA45AF01 panel is an AMOLED eDP panel that has backlight
control over the DP AUX channel. While it works almost correctly with the
generic "edp-panel" compatible, the backlight needs special handling to
work correctly. It is similar to the existing ATNA33XC20 panel, just with
a larger resolution and size.
Add a new "samsung,atna45af01" compatible to describe this panel in the DT.
Use the existing "samsung,atna33xc20" as fallback compatible since existing
drivers should work as-is, given that resolution and size are discoverable
through the eDP link.
