perf: add OMAP support for the new power events

The patch adds the new power management trace points for
the OMAP architecture.

The trace points are for:
- default idle handler. Since the cpuidle framework is
  instrumented in the generic way there is no need to
  add trace points in the OMAP specific cpuidle handler;
- SoC clocks changes (enable, disable, set_rate),
- power domain states: the desired target state and -if different-
  the actually hit state.

Because of the generic nature of the changes, OMAP3 and OMAP4 are supported.

Tested on OMAP3 with suspend/resume, cpuidle, basic DVFS.
