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

Fixes: 066a94e28a23 ("media: dt-bindings: media: Use graph and video-interfaces schemas")

Changes in v3:
1. Drop link-frequencies entirely (Sakari)
2. Add Conor's ack

Changes in v2:
1. Rework approach: decouple bindings from driver instead of fixing
   DTS example (Sakari)
