boards/nucleo-l412kb: enable ADC

[krzysztof-cabaj]

Contribution description

This PR enables ADC for nucleo-l412kb board.

I don't have access to this boards, but because ADC pinout is the same as for nucleo-l432kc (see board manual tables 15 and 16) code should works fine. I compile code without any warnings.

Testing procedure

Flash the board using tests/periph/adc and tests/periph/vbat programs.

The outputs should be similar to the ones presented in #21238 (comment)

Issues/PRs references

None.

Which testing 👀

I don't have access to this boards, [...]

But yeah, let's hope it works as it is similar enough.

[krzysztof-cabaj]

Thank you for your trust ... but as @crasbe notices I don't have this boards and only look at documentation for similar board and check if tests/periph/adc and tests/periph/vbat compile for this board with success.

BTW. There is probably some problem with Murdock - from few days all full merge at 2 o'clock failed, in most cases due to some bizzare timeouts. Moreover, failed test for this PR is associated with timeout, too ... and I don't think that this is this PR fault.

[crasbe]

Yes, that error is unrelated to your code. The timing tests are a bit finnicky lately which probably correlates to load on the CI servers.

I was waiting for a response from @maribu before putting it back on the queue.
