HID: add support for 2012 MacBook Pro Retina

commit b2e6ad7dfe26aac5bf136962d0b11d180b820d44 upstream.

Add support for the 15'' MacBook Pro Retina. The keyboard is
the same as recent models.

The patch needs to be synchronized with the bcm5974 patch for
the trackpad - as usual.

Patch originally written by clipcarl (forums.opensuse.org).
