[ANN] U-Boot v2023.10-rc3 released

Hey all,

It's release day and I've tagged and pushed -rc3, and will merge that to next as well shortly. Things should really stay stable now until release, so I'd really like to start seeing PRs for -next at this point.

In terms of a changelog, git log --merges v2023.10-rc2..v2023.10-rc3 contains what I've pulled but as always, better PR messages and tags will provide better results here.

I'm going to try and stay on schedule now and that means the rest of the rcs every other Monday, and with final release on October 2nd, 2023. Thanks all!
