[media] smiapp: Read link-frequencies property from the endpoint node
[media] smiapp: Read link-frequencies property from the endpoint node

The documentation stated that the link-frequencies property belongs to the
endpoint node, not to the device's of_node. Fix this.

There are no DT board descriptions using the driver yet, so a fix in the
driver is sufficient.
