Enhacement: Internal temperature Home Assistant discovery

[f-vicente]

Describe the bug
An enhacement related with #1125

Will be great a flag that enables the internal temperature to be published, and generates the appropriate HASS discovery.

At this moment you need to create the timmer to publish the variable value (like shown on #1125), then create the appropriate sensor manually in home assistant. Will be great if this could be automated.

Firmware:

• Version 1.17.553
• Chip/model: BK7231N

Sure, it's planned and I can add it for you, but first, are you aware that this internal temperature is not a perfect measurement and should not be really relied upon? As far as I know it' even has serious issue on one of the platforms. The fix is still pending.

Great!

Yes I know that the sensor is very inaccurate, but I like to have statistics about it, and use the values to trigger alarms if they get very high values that could reflect any problem. I only have bk7231n devices and those seem to work reasonably fine.
