drm/msm: update rsc mode_2 entry failure sequence

sde rsc mode_2 entry may fail due to sequence busy in
mode_0 or mode_1. It can be avoided by manually triggering
the f1 qtimer interrupt and execute the mode sequence.
This change tries to run the recovery sequence for 3 times
to avoid mode_2 entry failure.
