ARM: SoC fixes 

The latest and greatest fixes for ARM platform code. Worth pointing out are:
 
 - Lines-wise, largest is a PXA fix for dealing with interrupts on DT that was
   quite broken. It's still newish code so while we could have held this off,
   it seemed appropriate to include now
 - Some GPIO fixes for OMAP platforms added a few lines. This was also fixes for
   code recently added (this release).
 - Small OMAP timer fix to behave better with partially upstreamed platforms,
   which is quite welcome.
 - Allwinner fixes about operating point control, reducing overclocking in some
   cases for better stability.
 
 + a handful of other smaller fixes across the map.
