[PATCH 1/2] hrtimer: Remove hrtimer_clock_base::get_softirq_time()

[Mark McLoughlin]

Peter Zijlstra noticed this 8 months ago and I just noticed
it again.

hrtimer_clock_base::get_softirq_time() is currently unused
in the entire tree. In fact, looking at the logs, it appears
as if it was never used. Remove it.
