Many drivers ab(use) `select BACKLIGHT_CLASS_DEVICE` to avoid
dependency problems. This however makes it impossible for DRM
core to be able to add a dependency on ACPI_VIDEO. Switch users
of `select BACKLIGHT_CLASS_DEVICE` to `depends on BACKLIGHT_CLASS_DEVICE`.

Many DRM drivers (ab)use `select ACPI_VIDEO` and to avoid problems
will then select all the dependencies for ACPI_VIDEO. This creates
a soft dependency, but makes it very hard to use ACPI_VIDEO in DRM
core. Switch everything else over to use `depends on ACPI_VIDEO`
instead.

This series adds the ability to fetch the EDID through ACPI for laptop
panels. Drivers need to opt into the behavior.
In this series it's enabled by default for all eDP or LVDS panels with
AMDGPU and certain panels for Nouveau.
