[ANN] U-Boot v2022.07-rc1 released

Hey all,

It's release day and so here's v2022.07-rc1. There's a lot in here, and there's a few more things yet to come, hopefully this week, in terms of pull requests.

In terms of a changelog, git log --merges v2022.04..v2022.07-rc1 contains what I've pulled but as always, better PR messages and tags will provide better results here.

So we're now looking at regular releases every other Monday, and with final release on July 4th, 2022. Thanks all!
