Joel Fernandes a81d322647 ANDROID: sched/rt: schedtune: Add boost retention to RT ...

Boosted RT tasks can be deboosted quickly, this makes boost usless
for RT tasks and causes lots of glitching. Use timers to prevent
de-boost too soon and wait for long enough such that next enqueue
happens after a threshold.

While this can be solved in the governor, there are following
advantages:
- The approach used is governor-independent
- Reduces boost group lock contention for frequently sleepers/wakers

Note:
Fixed build breakage due to schedfreq dependency which isn't used
for RT anymore.
