boards: adafruit feather nrf52840 uf2 initalize USB at boot

[fkokosinski]

Make Adafruit Feather nrf52840 UF2 variants initialize USB by default.

Adafruit Feather nRF52840 UF2 variants have their USB enabled by default, and use the CDC ACM UART for the console. All other nRF52840 boards that use that, initialize their USB by default. This PR makes it so Adafruit Feather nRF52840 UF2 variants also do that.

Looks good to me.

Thanks for those links @jfischer-no. I get that in the end we'd prefer to have it done in a more tidy way.

But right now we have a target that is essentially not working correctly, so IMO we should:

1. first, go ahead with this PR which makes the target work correctly
2. and later, clean up CDC ACM configuration later (with the PR you linked)

This way we'd avoid keeping a non-working target in-tree and waiting for the more complex effort to land in order to sort this situation out.

WDYT?

If you were to read the contents of the linked issue and commit messages in the linked PR, you would realize that this PR is not a correct fix at all.

Closing because the issue this PR was addressing has been fixed in #81308.
