Amend the DT bindings for the Renesas SCI driver to allow describing
optional GPIO-controlled modem lines, which can be used where dedicated
modem lines are not available.

The property naming is dictated by the SERIAL_MCTRL_GPIO helpers.

Hi Geert,

I do not feel strongly about this but I wonder if it
would make sense to update the example with the new properties.

These are meant to be added to the board .dts file, not to the .dtsi files.
I can add an example if you like, let's hope nobody copies it blindly to a
.dtsi file...

Gr{oetje,eeting}s,

                        Geert
