ARM: dts: msm: Enable vmem_plus governor on 8996 



The current vmem governor does not scale up vmem clock
frequencies up to expected levels. This would result in
frame drops, especially during concurrent video sessions.
The new vmem governor fixes frame drops by ensuring that
the  vmem clock is always scaled one level below the video
core clock.
