Add the 350 MHz frequency support that can be used for display with
pixelclk of 50 MHz. The divider of 7 is important for LVDS output on
i.MX93. It is also usable for parallel output.

Can you use similar method to share 7" lvds for other boards also

I can try to unify this using a nexus connector node and unified labels.
But it looks like there is at least one dependency not yet applied in
[1] for this to actually work.

Can we apply this now and I will rework this once the driver core
changes have been merged? Or do you rather want me to wait until it has
landed?
