[PATCH] Add support for the Mid 2011 MacBook Air keyboard layout

[Dirk Hohndel]

When adding support for the MacBookAir4,x models in commit
5d922baa631058c7e37ae33e81c4d3e6437f8d1d Joshua Dillon overlooked
that they have a slightly different keyboard layout compared to the older
MacBook Air models. With this patch the function keys all work as
advertized, including keyboard brightness, etc.
