[ANN] U-Boot v2020.10 released

Hey all,

It is release day and here is the v2020.10 release. With this release we have a number of "please migrate to DM" warnings that are now 1 year past their warning date, and well past 1 year of those warnings being printed. It's getting up there on my TODO list to see if removing features or boards in these cases is easier.

In terms of a changelog, git log --merges v2020.10-rc5..v2020.10 or git log --merges v2020.07..v2020.10

The merge window is once again open and I plan to tag -rc1 on Monday, October 26th, bi-weekly -rcs thereafter and final release on January 11th, 2021.

I am merging the next branch to master shortly and will send a separate email when that is done.
