media: dt-bindings: ov8856: decouple lanes and link frequency from driver

The data lanes and link frequency were set to match existing Linux driver
limitations, however bindings should be independent of chosen Linux
driver support.

Decouple these properties from the driver to match what is actually
supported by the hardware.

This also fixes DTS example:

  ov8856.example.dtb: camera@10: port:endpoint:link-frequencies:0: [360000000] is too short
