Thomas Gleixner 03a90b9a6f timekeeping: Maintain ktime_t based offsets for hrtimers ...

This is a backport of 5b9fe759a6

We need to update the hrtimer clock offsets from the hrtimer interrupt
context. To avoid conversions from timespec to ktime_t maintain a
ktime_t based representation of those offsets in the timekeeper. This
puts the conversion overhead into the code which updates the
underlying offsets and provides fast accessible values in the hrtimer
interrupt.
