[v2,0/4] clocksource: Add MCT support for ARTPEC-8

Message

This series add supports for the timer block on ARTPEC-8.  The block itself is
fully compatible with the existing exynos4210-mct driver.  The ARTPEC-8 SoC
uses this block from two separate processors running Linux (AMP) so it needs
some extra code to allow this sharing.

v2:
- The series is now rebased on top of Krzysztof's patch "dt-bindings: timer:
  exynos4210-mct: describe known hardware and its interrupts".
- Combine the Kconfig change and the local timer change into one series
- Use devicetree property rather than module parameter for the local timer handling
- Add specific compatible with the correct number of interrupts.
