Revert "ANDROID: sched/cpuset: Add vendor hook to change tasks affinity"

This reverts commit 4d1ac6a1 as it
causes merge conflicts, and build conflicts in 6.1-rc1 due to upstream
cpuset changes.  If this is needed in 6.1, it will have to be reworked
and forward ported in a different way as the structure information has
been changed in 6.1.
