msm: mdss: Reduce display commit latency caused by deep CPU idle

During heavy parts of the display commit process, the CPU can enter a
deep idle state and cause the commit latency to increase significantly.

Forcing the CPU to only use idle states with latencies under 100 us
during the critical portions of the commit process fixes the high commit
latency.
