[PATCH v2 07/37] tracing: hrtimer: Take all clock bases and modes into account

[Anna-Maria Gleixner]

So far only CLOCK_MONOTONIC and CLOCK_REALTIME were taken into account as
well as HRTIMER_MODE_ABS/REL in hrtimer_init tracepoint. The query for
detecting timer mode ABS or REL is not valid, since the introduction of
HRTIMER_MODE_PINNED.

HRTIMER_MODE_PINNED is not evaluated in hrtimer_init() call. But for the
sake of completeness print all given modes.
