[PATCH V3 00/13] ARM: OMAP: DMTIMER fixes

This series includes several fixes for the OMAP DMTIMER driver. This is
based upon Tony Lindgren's current master branch [1].

Tested on OMAP5912 OSK, OMAP2420 H4, OMAP3430 Beagle and OMAP4430 Panda.
Testing includes ...
1. Booting kernel on above boards
2. Set date and ensuring time of day is correct after 24 hours
3. Checking the timer counter is incrementing when configuring and starting
   a timer
4. Checking the timer overflow interrupt when timer expires.
5. Using different clock sources to operate the timer with.
6. Running a loop test overnight that continually runs test #3 and #4 for
   each available timer

This has also been boot tested on the AM335x Beagle Bone.

V3 changes:
- Combined patches #2 and #3 in version 2 series into single patch.
- Updated errata i103/i767 workaround to pass errata information via
  platform data to avoid using cpu_is_xxxx() macros in dmtimer driver.
