After the recent backlight changes acpi_video# backlight devices are only
registered when explicitly requested from the cmdline, by DMI quirk or by
the GPU driver.
This means that we no longer get false-positive backlight control support
advertised on desktop boards.
Remove the 3 DMI quirks for desktop boards where the false-positive issue
was fixed through quirks before. Note many more desktop boards were
affected but we never build a full quirk list for this.
