USB: EHCI: log a warning if ehci-hcd is not loaded first

commit 9beeee6584b9aa4f9192055512411484a2a624df upstream

This patch (as1139) adds a warning to the system log whenever ehci-hcd
is loaded after ohci-hcd or uhci-hcd.  Nowadays most distributions are
pretty good about not doing this; maybe the warning will help convince
anyone still doing it wrong.
