Steven Rostedt 74f37f2a24 PM: cpufreq: powernv/tracing: Move powernv_throttle trace event

[ Upstream commit 647fe16b46 ]

As the trace event powernv_throttle is only used by the powernv code, move
it to a separate include file and have that code directly enable it.

Trace events can take up around 5K of memory when they are defined
regardless if they are used or not. It wastes memory to have them defined
in configurations where the tracepoint is not used.
