Quoting Maulik Shah (2020-04-12 07:50:01)
> TCSes have previously programmed data when rpmh_flush() is called.
> This can cause old data to trigger along with newly flushed.
> 
> Fix this by cleaning SLEEP and WAKE TCSes before new data is flushed.
> 
> With this there is no need to invoke rpmh_rsc_invalidate() call from
> rpmh_invalidate().
> 
> Simplify rpmh_invalidate() by moving invalidate_batch() inside.
