Hey guys, this is essentially a revert of:
commit f36f83f947ede547833e462696893f866df77324
Author: Namhyung Kim <namhyung.kim@lge.com>

perf sched: Move struct perf_sched definition out of cmd_sched()
For some reason it consumed quite amount of compile time when declared
as local variable, and it disappeared when moved out of the function.
Moving other variables/tables didn't help.
On my system this single-file-change build time reduced from 11s to 3s.
