Home assistant mqtt wifi_strength should be in dB or dBm, not %

[pkishino]

Describe the bug As per a few versions back, the unit of measure for wifi signals was finalized as dB or dBm. The config script here still uses % which triggers an issue with home assistant during discovery. The fix would be to stick to using dB which is, what I believe, is the default for the camera (the % uses a conversion formula)

To Reproduce current example wifi_strength config:

{
  "availability_topic": "yicam/status",
  "payload_available": "online",
  "payload_not_available": "offline",
  "device": {
    "identifiers": [
      "yi-cam"
    ],
    "manufacturer": "YI",
    "model": "YI Hack",
    "name": "Yi Camera",
    "sw_version": "0.3.7"
  },
  "qos": 1,
  "device_class": "signal_strength",
  "icon": "mdi:wifi",
  "state_topic": "yicam/telemetry",
  "name": "Yi Camera Wlan Strengh",
  "unique_id": "yi-cam-wlan_strength",
  "value_template": "{{ ((value_json.wlan_strength|int) * 100 / 70 )|int }}",
  "unit_of_measurement": "%",
  "platform": "mqtt"
}

Expected behaviour the above details should be something as below: "unit_of_measurement": "dB",

@pkishino Looking closer into recent fixes, this would not be relevant and the current unit is correct
