Johan Hovold 570dfa7c55 greybus: connection: add unidirectional enabled state
Add a new connection state ENABLED_TX in which only outgoing operations
are allowed.

This allows drivers to query the device during probe before allocating
their state containers without having to worry about racing incoming
requests.
