sched/pelt: Remove redundant cap_scale() definition

deggeman · Peter Zijlstra · commit 844eb6458fac · 2020-06-15T14:10:01.000+02:00
Besides in PELT cap_scale() is used in the Deadline scheduler class for scale-invariant bandwidth enforcement. Remove the cap_scale() definition in kernel/sched/pelt.c and keep the one in kernel/sched/sched.h.
