[PATCH v6 1/5] drm: Stop using `select ACPI_VIDEO` in all drivers

From: Mario Limonciello
Date: Wed Feb 14 2024 - 16:59:06 EST

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.

Choose this option if you have a recent AMD Radeon graphics card.
