USB: xhci: Add correct email and files to MAINTAINERS entry.
commit 36d0344c254a7b333272757f858c403ea3a2d29f upstream.
Add the xHCI driver files to its MAINTAINERS entry so that I'm Cc'd on
cleanup patches. Update the email address to one I actually use for
sending patches and responding to Linux mailing list emails.
