Subject: drm: mali-dp: Turn off CRTC vblank when removing module.
Git-commit: 57085dca982bd042f64aa23f5e03747595b2c8c0
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

When unbinding the mali-dp driver the drm_vblank_cleanup() function
warns us that the vblanks are still enabled. Fix that by calling
drm_crtc_vblank_off() in the malidp_unbind() function.
