ACPI: video: Do not export a non working backlight interface on MSI MS-7721 boards
Despite our heuristics to not wrongly export a non working ACPI backlight interface on desktop machines, we still end up exporting one on desktops using a motherboard from the MSI MS-7721 series. I've looked at improving the heuristics, but in this case a quirk seems to be the only way to solve this. While at it also add a comment to separate the video_detect_force_none entries in the video_detect_dmi_table from other type of entries, as we already do for the other entry types.
