Revert "ANDROID: sched: Enable idle balance to pull single task towards cpu with higher capacity"



This reverts commit f2fce2f4.

We want to back-out the eas-dev merge that happened in the tree after
5.3-rc1 as those patches "should" all be in Linus's tree now.

This is done to handle the merge conflicts with 5.4-rc1.
