Use panel-dpi driver instead of the deprecated tilcdc-panel driver in preparation for removing the tilcdc-panel driver and binding.

Yes, I know this but I still wanted to try and begin a discussion on this, as I really thought it is not a good idea to add and maintain an new non-standard panel driver solely for this tilcdc panel binding. I have gathered more arguments on this topic on next patch.
Stuffing DTS change in the middle of the driver change tries to hide impact, which is not nice on its own.
As it needs driver change before the removal for not breaking things it can't be done at the beginning of the series. Regards, -- Köry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
