Set entity category to configuration for Sonoff TRVZB open/close degree entities

[blacknell]

Closes #7564

Currently, the entity category is not set for open and close degree meaning the controls display in dashboards and elsewhere in HA. These should be configuration entities managed through admin UI.

thanks!

@Koenkk - I've since noticed a whole bunch more sensor entities that seem to me "useless" to the average end user. I think they should move to be diagnostic category rather than default sensor category. Their function isn't documented anywhere by Sonoff.

I have 14 TRV's so that's 56 entities that get added to auto dashboards which is silly.

If you're in broad agreement I'll create a fresh PR and submit that (move them to diagnostic).

They are:-

• Closing steps
• Valve closing limit voltage
• Valve motor running voltage
• Valve opening limit voltage

There's also a read-only sensor called Frost Protection Temperature that is by default disabled but listed as a Sensor. But this is superfluous as it just reflects (if enabled) the value of the writeable control entity of the same name. I could investigate this and find out why it's duplicated and remove.

Sounds good!
