Subject: [PATCH 1/1] acpi video: force native for some T2 macbooks

The intel backlight is needed for these.

MacBookPro15,2/4 or MacBookPro16,3 or MacBookAir8,1/2 might also need
this so I'm not going to be submitting this upstream  yet

mbp16,3 was reported not to have this issue for 6.5.8 at least.
