Add DT nodes needed for the mini DP connector. The DP is driven by
sn65dsi86, which in turn gets the pixel data from the SoC via DSI.

Thanks for your patch!

i.e. will queue in renesas-devel for v6.3, with the mini-dp-con node
moved up.

Moving up while applying to preserve sort order...

Ideally, this needs pinctrl for the intc_ex irq0 pin.
Unfortunately[1] is still in limbo as the naming of the alternate pins
is inconsistent.
