greybus: connection: add name field
Add a name field to connections that can be used in log messages.
A connection always belongs to a host-device (bus) and can be uniquely
identified by its host-device cport id, but include remote interface and
cport id nonetheless on the following format:
<hd_cport_id>/<intf_id>:<cport_id>
The remote interface and cport id will be zero for static connections.
