Pull timer updates from Thomas Gleixner:
 "Time, timers and timekeeping updates:

   - No core updates

   - No new clocksource/event driver

   - A large rework of the ARM architected timer driver to prepare for
     the support of the upcoming ARMv8.6 support

   - Fix Kconfig options for Exynos MCT, Samsung PWM and TI DM timers

   - Address a namespace collison in the ARC sp804 timer driver"
