media: dt-bindings: adv748x: make data-lanes property mandatory for CSI-2 endpoints

The CSI-2 transmitters can use a different number of lanes to transmit
data. Make the data-lanes mandatory for the endpoints that describe the
transmitters as no good default can be set to fallback on.

The digital output port nodes must contain at least one endpoint. The digital output port nodes, when present, shall contain at least one
endpoint. Each of those endpoints shall contain the data-lanes property as
described in video-interfaces.txt.
Required source endpoint properties:
- data-lanes: an array of physical data lane indexes
The accepted value(s) for this property depends on which of the two
sources are described. For TXA 1, 2 or 4 data lanes can be described
while for TXB only 1 data lane is valid. See video-interfaces.txt
for detailed description.
Ports are optional if they are not connected to anything at the hardware level. Ports are optional if they are not connected to anything at the hardware level.
