Subject: drm/panel: simple: fix vertical timings for Innolux AT043TN24
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.

Subject: drm/panel: simple: add bus flags for Innolux AT043TN24
For LCD interface controllers that support configuring polarity of
pixel clock and data enable signal, specify bus flags in the panel
descriptor.

Subject: drm/panel: simple: add Toshiba LT089AC19000
Only exposes a single mode and not a complete display timing, as
the datasheet is rather vague about the minimum/maximum values.
