Platform entry must be unique

[stanislaspiron]

Describe The Bug:

when I migrated from accessory to platform, I have following log message:

The dynamic platform Livebox from the plugin homebridge-livebox-tv seems to be configured multiple times in your config.json. This behaviour was deprecated in homebridge v1.0.0 and will be removed in v2.0.0!

To Reproduce:

configure 2 llivebox platform entries:

        {
            "ip": "192.168.1.96",
            "platform": "Livebox"
        },
        {
            "ip": "192.168.1.94",
            "platform": "Livebox"
        }

Expected behavior:

support a list for devices in platform entry:

        {
            "platform": "Livebox",
            "tvs": [
                {
                     "ip": "192.168.1.94"
                },
                {
                     "ip": "192.168.1.99"
                }
            ]
        }

• Plugin Version: 0.3.0
• Homebridge Version: 1.6.0
