[PATCH v3 4/9] of: property: fw_devlink: Add support for "depends-on"

[Herve Codina]

The generic "depends-on" property expresses a simple functionnal
dependency. The "depends-on" consumer must be available before
the "depends-on" provider.

Handling "depends-on" as a fw_devlink matches this dependency in
a generic way.
