Subject: [PATCH 20/46] kernel: Move prototype declaration to header file
 sched/sched.h from sched/core.c

Move prototype definition of function to header file
kernel/sched/sched.h from kernel/sched/core.c because it is used by more
than one file.

This eliminates the following warning in kernel/sched/deadline.c:62:6:
kernel/sched/deadline.c:62:6: warning: no previous prototype for ‘init_dl_bw’ [-Wmissing-prototypes]
