driver core: Change delimiter in devlink device's name to "--"

The devlink device name is of the form "supplier:consumer". But ":" is
fairly common in device names and makes it visually hard to distinguish
supplier and consumer. So, replace it with "--" to make it easier.

 Description:
                Provide a place in sysfs for the device link objects in the
                kernel at any given time.  The name of a device link directory,
-               denoted as ... above, is of the form <supplier>:<consumer>
+               denoted as ... above, is of the form <supplier>--<consumer>
                where <supplier> is the supplier device name and <consumer> is
                the consumer device name.
