Hi!

This is a resurrection of the patchset initially posted by Pankaj Dubey
about 1.5 year ago:
https://www.spinics.net/lists/arm-kernel/msg541517.html

I fixed the following issues that prevented the merge of the original
patchset:
- added fallback to scu_a9_get_base() when no SCU DT node is available,
  what fixed compabitlity issue with old DTBs
- fixed non-SMP build
- keep SCU mapping permanent, to avoid costly DT lookup in CPUidle hot
  path and calling ioremap with IRQs disabled (also in CPUidle calls)

This patchset has been tested on the following Exynos4-based boards:
Universal_C210 (4210-EVT0), Origen (4210), Trats (4210), Trats2 (4412),
OdroidU3 (4412). In all cases it works fine.
