[U-Boot] About the pull request and patchwork

Hi all,

I've noticed that there are many pull request logged inside the patchwork. The most of the pull request has been processed but not been removed in patchwork. This make a lot of useless pull request log in the patchwork and made more difficult to tracking other patches.

I think if we (custodians) could assigned the pull request as "accept" or something after Wolfgang has pull the commits from downstream will be good. What do you guys think about it?
