[Freedreno] [PATCH 1/3] drm/msm/mdp5: Configure PP_SYNC_HEIGHT to double the vtotal

Leaving this at a close-to-maximum register value 0xFFF0 means it takes very long for the MDSS to generate a software vsync interrupt when the hardware TE interrupt doesn't arrive. Configuring this to double the vtotal (like some downstream kernels) leads to a frame to take at most twice before
