ARM: SoC fixes

We didn't have a batch last week, so this one is slightly larger.
 
 None of them are scary though, a handful of fixes for small DT pieces,
 replacing properties with newer conventions.
 
 Highlights:
 
  - N900 fix for setting system revision
  - onenand init fix to avoid filesystem corruption
  - Clock fix for audio on Beaglebone-x15
  - Fixes on shmobile to deal with CONFIG_DEBUG_RODATA (default y in 4.6)
 
  + misc smaller stuff.
