tracing, perf: Add more power related events
This patch adds new generic events for dynamic power management
tracing:
- clock events class: used for clock enable/disable and for
clock rate change,
- power_domain events class: used for power domains transitions.
The OMAP architecture will be using the new events for PM debugging,
however the new events are made generic enough to be used by all
platforms.
