From: Fabio Estevam festevam@denx.de
Since commit 63b0cd30b78e ("media: ov2680: Add bus-cfg / endpoint property verification") the ov2680 no longer probes on a imx7s-warp7:
ov2680 1-0036: error -EINVAL: supported link freq 330000000 not found ov2680 1-0036: probe with driver ov2680 failed with error -22
As the 'link-frequencies' property is not mandatory, allow the probe to succeed by skipping the link-frequency verification when the property is absent.
