[PATCH] Add power/gpu_frequency tracepoint.

Historically there is no common trace event for GPU frequency, in downstream Android each different hardware vendor implements their own way to expose GPU frequency, for example as a debugfs node. This patch standardize it as a common trace event in upstream linux kernel to help the ecosystem
