ACPI / video: Add quirks for the Dell Precision 7510
The Dell Precision 7510 has a broken acpi-video implementation. The backlight control bits work, but when the brightness is changed via the acpi-video interface the backlight flickers annoyingly before settling at the new brightness, switching to using the native interface fixes the flickering so add a quirk for this (the vendor interface can not change the brightness at all).
