Matt Wagantall 0fe22de096 trace: power: add cpu_frequency_switch_{start, end} ...

It is sometimes useful to profile how long CPU frequency switches
take, since they often involve variable overhead (PLL lock times,
voltage increase time, etc.). Add additional traces to to make this
possible.

Since the overhead involved may differ based on the frequencies
being switched between, record both the start and the end frequencies
as part of the trace.
