ALS and other new functions

Matthew,

This is partially a resend of the previous patch-set (first 7 patches) plus additional changes to queue up for 3.15.

The largest change is support for ALS on recent Vaios. The work is a respin of what Javier Achirica and Marco Chiappero had done almost 3 years ago but ported to IIO (Javier did that).
The downside is that when ALS control is enabled, changes to the backlight via _BCM become notifications to SNC that should instead act. Unfortunately there is no obvious way to get the brightness level that was requested. To workaround that I have added a notification callback to the backlight driver. It seems a generally useful mechanism and is definitely useful in this case. The ALS patch has still some rough edges but it has been used by many people for years now.

Javier Achirica (9):
sony-laptop: add support as Fn+1 as a hot key
sony-laptop: Add support for lid resume settings on Vaio Pro
