Subject: drm/msm/mdp5: don't use autosuspend
Git-commit: 3c352b66905b29689bbf1c8e3722c26de65f086d
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

It's only likely to paper over bugs.  Unlike the gpu, where we want to
keep things alive a bit longer in expectation of the next frame's
submit, when the display is shut down we can power off immediately.
