ARM: SoC fixes

Browse Source 
A few fixes that have trickled in through the merge window:
 
  - Video fixes for OMAP due to panel-dpi driver removal
  - Clock fixes for OMAP that broke no-idle quirks + nfsroot on DRA7
  - Fixing arch version on ASpeed ast2500
  - Two fixes for reset handling on ARM SCMI
