Subject: drm/panel: simple: fix vertical timings for Innolux AT043TN24
Git-commit: a483159d2b5238b69ef6a3310a4aa61b0dd496c3
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The vsync length should be 10 lines, as specified in the data sheet.
This gets the actual refresh rate closer to nominal 60 Hz given the
9 MHz pixel clock.
