Possibility to add Yamaha AV-receivery explicitly via their IP

Hi,

i have a Yamaha RX V473 which i want to add to Home Assistant. For some reason i haven’t figured out yet it does not respond to SSDP probes. The yamaha media_player component relies on rxv, which has a possibility to explicitly state the device’s IP address if SSDP scanning fails (for whatever reason). When i open a python console and import rxv and create a receiver object with an explicit IP address, i can control the device via this console just fine.

So my feature request is that the yamaha media_player component should have a config flag for the receiver’s IP so that it adds it without autodiscovery (like the google cast component for example).
