bus: arm-ccn: Use hrtimer_start() again
hrtimer_start() will no longer defer already expired timers to the softirq in 4.2, and the __hrtimer_start_range_ns() function is getting removed, causing build errors when both the tip tree and the arm-ccn changes are merged. This changes the code back to using hrtimer_start, which will do the right thing after this branch gets merged with the timers update from tip. As pointed out after a discussion on the mailing list, the result will not be worse than the what was there before you pulled my updates, as the code was using normal hrtimer_start(). It's just when I realised that it should be pinned I looked at what x86 uncore pmu is doing and shamelessly (and probably a bit mindlessly) copied the "do not wakeup" version from there.
