trace: power: add trace_clock_set_parent
Adds a new trace event to be called from clk_set_parent. Some
cpufreq drivers, including Tegra, reparent the cpu clock to a
slower clock while the main pll is relocking, tracing
clk_set_parent allows traces to show how for long the cpu is
running slower.
Uses a separate TRACE_EVENT instead of the clock event class to
allow the event to contain string names for the child and the
parent.
