Merge tag 'pxa-for-4.4' of https://github.com/rjarzmik/linux into next/cleanup 

This is the pxa changes for v4.4 cycle.

This cycle is bigger than usual :
 - magician was greatly enhanced (new IPs discovered, ...)
 - almost all legacy board files have been updated to the
   new PWM API (mostly for backlight control)
 - some minor fixes in raumfeld, z2 and mioa701
