MAINTAINERS: usb, update Peter Korsgaard's entries

<[email protected]>:
      Sorry, no mailbox here by that name. (#5.1.1)

Peter says:
** Ahh yes, it should be changed to [email protected].

However he also says:
** I haven't had access to c67x00 hw for quite some years though, so maybe
** it should be marked Orphan instead?

So change as he wishes.
