ARM: SoC fixes

Browse Source 
This is a slightly larger batch of fixes that we've been sitting on a few
 -rcs. Most of them are simple oneliners, but there are two sets that are
 slightly larger and worth pointing out:
 
  - A set of patches to OMAP to deal with hwmod for RTC on am33xx (beaglebone
    SoC, among others). It's the only clock that ever has a valid offset of 0,
    so a new flag needed introduction once this problem was discovered.
 
  - A collection of CCI fixes for performance counters discovered once people
    started using it on X-Gene CPUs.
