of: property: Improve finding the consumer of a remote-endpoint property

[ Upstream commit f4653ec9861cd96a1a6a3258c4a807898ee8cf3c ]

We have a more accurate function to find the right consumer of a
remote-endpoint property instead of searching for a parent with
compatible string property. So, use that instead. While at it, make the
code to find the consumer a bit more flexible and based on the property
being parsed.
