ACPI: video: Add backlight=native quirk for Dell OptiPlex 7770 AIO
The Dell OptiPlex 7770 AIO needs the same quirk as the 7760 AIO. The
backlight can be controlled with the native controller, intel_backlight,
but not with dell_uart_backlight.
I dumped the DSDT using acpidump, acpixtract and iasl, and confirmed
that it contains the DELL0501 device. When loading the
dell_uart_backlight driver with `rmmod dell_uart_backlight`, `modprobe
dell_uart_backlight dyndbg`, it reports "Firmware version: GL_Re_V18".
