Revert "drm/panel-edp: Add SDC ATNA45AF01"

This reverts commit 8ebb1fc2e69ab8b89a425e402c7bd85e053b7b01.

The panel should be handled through the samsung-atna33xc20 driver for
correct power up timings. Otherwise the backlight does not work correctly.

We have existing users of this panel through the generic "edp-panel"
compatible (e.g. the Qualcomm X1E80100 CRD), but the screen works only
partially in that configuration: It works after boot but once the screen
gets disabled it does not turn on again until after reboot. It behaves the
same way with the default "conservative" timings, so we might as well drop
the configuration from the panel-edp driver. That way, users with old DTBs
will get a warning and can move to the new driver.
