[U-Boot-Users] FYI, updated CustodianGitTrees page

The major change was adding a "maintenance" bullet to the list and add a 
tip on how to remove unnecessary branch labels from the remote 
repository.  We (custodians) inherited some branches from a while ago 
and I wanted to clean up the unused branches, had to figure out how.

Hint of you want to do the same cleanup on your repositories:

# show all branches:
git branch -a

# kill off the obsolete ones:
git push ssh://gu-fdt at git.denx.de/u-boot-fdt.git :heads/dzu at denx.de
git push ssh://gu-fdt at git.denx.de/u-boot-fdt.git :heads/wd at denx.de
git push ssh://gu-fdt at git.denx.de/u-boot-fdt.git :heads/testing-4xx_enet
git push ssh://gu-fdt at git.denx.de/u-boot-fdt.git :heads/testing-NAND
git push ssh://gu-fdt at git.denx.de/u-boot-fdt.git :heads/testing-USB

While I was in the page, I also changed all the "git+ssh" to "ssh" - 
unless I'm grossly confused, newer git versions no longer need to use 
the "git+" hack.  I also changed the "gu-fdt" ssh user names to the 
generic form "git-<subrepo>" so people cutting and pasting get a better 
hint if they forget to fix the login name.
