sched/uclamp: Make asym_fits_capacity() use util_fits_cpu()

[ Upstream commit a2e7f03ed28fce26c78b985f87913b6ce3accf9d ]

Use the new util_fits_cpu() to ensure migration margin and capacity
pressure are taken into account correctly when uclamp is being used
otherwise we will fail to consider CPUs as fitting in scenarios where
they should.

s/asym_fits_capacity/asym_fits_cpu/ to better reflect what it does now.
