ACPI: video: Add Apple GMUX brightness control detection
On Apple laptops with an Apple GMUX using this for brightness control,
should take precedence of any other brightness control methods.
Add apple-gmux detection to acpi_video_get_backlight_type() using
the already existing apple_gmux_present() helper function.
This will allow removig the (ab)use of:
acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);
Inside the apple-gmux driver.
