[PATCH 06/89] sched/topology: Split out scheduler topology interfaces from into

The vast majority of sched.h users does not require the topology types and interfaces, so split them out into a separate header, and include them in the .c files that require them. This reduces the size of linux/sched.h by ~6%. Cc: Peter Zijlstra Cc: Mike Galbraith Cc: Thomas Gleixner Cc: Linu
