allwinner: Added support for allwinner H616 processor

[didiercrunch]

Added support for the allwinner H616 processor. Apparently, this also works for H618 processor.

Helps with #57 but doesn't not completely fix it.

Thanks a lot for the contribution!

I see a few failures unrelated to your change on the CI, I'll take a look to try to fix these. The PR will fail for the license header check at least, so you'll want to fix that.
A few changes requested, nothing significant.

I fixed the checks on origin/main, can you rebase and push again? Thanks!

Did you figure out why the checks still fail? Do you want help with diagnosing the problem?

Sounds good, thanks again!

There's a test failure to fix on Windows and then it's good to go.

@didiercrunch Thanks for this. I was working on creating an orange pi variation for H616, and I just found your PR.

I'm working on an Orange Pi Zero 2W, and your work may help me (at least to figure what else I should fix)
