Fix Nimly smart lock mains-powered capability

[uvNikita]

Proposed change

Add nimly smart lock quirk
Clears the mains powered mac capability flag since lock is battery powered.

Note that after quirk is applied, ZHA reports that my lock has 20% remaining battery, but when I query PowerConfiguration/battery_percentage_remaining attribute it reports 41%.
Not sure where ZHA gets 20% from.

See picture below:

Additional information

Tested on NimlyPro model.

I didn't add tests since I'm not sure how to test quirks v2, e.g. assert_signature_matches_quirk. Also not sure how to test node descriptor and power source specifically.

So it would be great with some direction on this if tests are required :)

Tests aren't really required for this. All good.

when I query PowerConfiguration/battery_percentage_remaining attribute it reports 41%.
Not sure where ZHA gets 20% from.

battery_percentage_remaining goes from 0 to 200. 200 means 100%. ZHA remaps it.
Some manufacturers also miss that and use 100 for 100%, which is wrong. There's a doubling power configuration cluster which doubles that attribute value before it reaches ZHA. We can also use that if the manufacturer made the same mistake.

Thanks!

Thanks for the review and the explanation about battery levels. I'll try to replace the battery and see if it will report the correct value. If not, I'll open another PR 🙂
