[PATCH v6 2/5] drm: Stop using `select BACKLIGHT_CLASS_DEVICE`

[Mario Limonciello <mario.limonciello@amd.com>]

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`.
