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

[ Upstream commit 295991836b23c12ddb447f7f583a17fd3616ad7d ]

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

commit 7dc918daaf29 ("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.
