Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

crtc->config points to the old crtc state at the point
display.crtc_disable() is called, so use the more descriptive pointer
instead.

v2:
- Convert one remaining instance of the ptr in the function. (Ville)
