[PATCH 1/4] sched/fair: Move max_cfs_quota_period decl and default_cfs_period() def from fair.c to sched.h

[Tejun Heo <tj@kernel.org>]

max_cfs_quota_period is defined in core.c but has a declaration in fair.c.
Move the declaration to kernel/sched/sched.h. Also, move
default_cfs_period() from fair.c to sched.h. No functional changes.
