We can see myq on the network to tell them to configure
it, but since the device will not give up the account it is
bound to and there can be multiple myq gateways on a single
account, we avoid showing the device as discovered once
they already have one configured as they can always
add a new one via "+"
* Add a config flow for myq
* Discovered by homekit
* Fix gates being treated as garage doors
* Offline devices now show as unavailable
* Homekit flow
* strip out icon
* return -> raise
