[PATCH v2 0/3] ARM: vf610: Fix/add clocksource

This patchset came out of need for a clocksource which supports shutdown.
In the first version I proposed to just replace the current clocksource
with the ARM Global Timer and even proposed to remove the PIT clocksource
driver. But Bill Pringlemeir brought up a reasonable point why we should
keep the PIT clocksource.

Since we need shutdown support for suspend/resume, I added another patch
which fixes shutdown functionality for the PIT driver. Now it's possible
to use suspend/resume functionality with each of the two clocksources.

Changes in v2:
- Added shutdown support for PIT clocksource (and hence clocksource
  maintainers as receipient).
- Create Kconfig entries which allow to choose between the two
  clocksources
- Clarified commit message
- Renamed device tree node to "timer"
