[ANN] U-Boot v2021.01-rc2 released

Hey all,

It's regular release day and I'm back on schedule, so here's -rc2.

There's a few small'ish things outstanding in my queue, and a queue of things building up for -next already. I'm going to try and make sure what I pull in, even when a clean-up, is as close as can be to the obviously correct side of things. Yes, this should always be the case, I'm just going to try and hold myself to expectations a bit harder.

In terms of a changelog, git log --merges v2021.01-rc1..v2021.01-rc2 contains what I've pulled but as always, better PR messages and tags will provide better results here.

I do have my reminders setup for doing -rc releases every other Monday from here on out and final release on January 11th, 2021. Thanks all!
