The display target feature gates every DRM module, but it says nothing useful: it is set on ten targets, so a mediatek/mt7623 board can have a display while a filogic board with a MIPI DBI panel cannot, and rockchip claims it for a NanoPi R2S as much as for a Rock 5B. Whether a board drives a panel is a per-device choice, not a property of the SoC family. The DRM and V4L2 nodes also end up 0600 root:root, so a display server runs as root or not at all. Add a video-support package which allocates the video and video-capture groups and installs the hotplug rules for the DRM and V4L2 nodes, and make the modules depend on it. The dependency is a plain one, not a select, so the modules are offered once the feature is chosen. Targets whose display drivers are built into the kernel carry the package in DEFAULT_PACKAGES, since no module pulls it in for them, and the one device profile that ships a DRM module on another target lists it directly. DISPLAY_SUPPORT stays for now, so this changes no existing selection. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
