Jadard JD9365DA-H3 is WUXGA MIPI DSI panel and it support TFT
dot matrix LCD with 800RGBx1280 dots at maximum.

Add support for it.

Look like I wrapped the wrong text, maybe this copy came from vendor
code. Yes, the datasheet mentioned this as WXGA resolution.

Thanks for this. I will correct it.

Yes, chongzhou,cz101b4001 panel which used JD9365DA-H3 controller IC.
Though JD9365DA-H3 itself is not a direct panel, we usually denote
controller IC as panel driver as these are part of Linux DRM panel and
as its own compatible "jadard,jd9365da-h3"

Thanks,
Jagan.
