[PATCH v2 7/9] hrtimer: Use hrtimer_cb_get_time() helper

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

Various other helpers contain open-coded implementations of
hrtimer_cb_get_time(). This prevents refactoring the implementation.

Reuse the existing helper.

For this to work, move hrtimer_cb_get_time() a bit up in the file and also
make its argument 'const'.
