sched/walt/core_control: disable need_all_cpus()

Browse Source 
need_all_cpus() was put in place in past products, so that silver
isolation could be enabled and disabled based upon the window
size, as a work around for lack of user-space controls for
disabling/enabling core_control. This blocks the ability to
isolate silver cores for lower window sizes, which is a valid
case that should be allowed for most products.

Cleanup the code for need all cpus, such that silver core control
may be used.
