ACPI: video: force native for Apple MacbookPro11,2 and Air7,2 



There is a bug in the Macbook Pro 11,2 and Air 7,2 firmware similar to
what is described in:

commit 7dc918da ("ACPI: video: force native for Apple MacbookPro9,2")

This bug causes their backlights not to come back after resume.

Add DMI quirks to select the working native Intel firmware interface
such that the backlght comes back on after resume.
