The waveshare 7" 800x480 panel is a clone of Raspberry Pi 7" 800x480 panel
It also uses a Toshiba TC358762 DSI to DPI bridge chip but it needs different
timing from Raspberry Pi panel. Add new timing for it.

Hi Shengyang,
The patch itself LGTM, but in case you have to put out a new revision,
can you please use the "drm/panel: <driver name>:" prefix format that
other drm/panel commits use?

Thanks for your suggestion. The prefix format will be used if we have next version.
btw, referring to the suggestions, we are going to try other timing from panel-simple
in our platform. Maybe we are not necessary to submit new version.
Thanks a lot
