What the driver is not relevant. Please define all possible

I wrote this as to document the hardware (there is no datasheet around and
I fear that findings will be forgotten one day)... but if you say it's
not relevant...
...well, then I can as well just write it in my local notes and remove the info
from here.

Also, I'm sorry for the *very* late reply. I've been busy quite a lot
in these days!
By the way, I'll push a v3 for this one ASAP!

The frequency needs to come from DT; it's not a property of the sensor.

I think we've used to specify the number of lanes if it's configurable,
instead of having defaults. I'd do the same here, i.e. require data-lanes.

- but 5948H x 4140V is more than 8 MP.
