[PATCH 13/15] video: simple_panel: Add tfc_s9700rtwv43tr_01b

[Markus Schneider-Pargmann (TI.com)]

Add timing data for tfc_s9700rtwv43tr_01b from Linux to the simple-panel
driver. To support hardcoded timing data as Linux does, add a new struct
simple_panel_drv_data which holds a struct display_timing pointer as
well. The hardcoded timing data is preferred over DT parsing.
