Alan Stern d8f12ab5d9 USB: UHCI: disable remote wakeup when it's not needed 
This patch (as1084b) fixes the way uhci-hcd handles polling and
remote wakeups for its root hubs.  When remote wakeup is disabled,
neither interrupts nor polling should be enabled during a root-hub
suspend.  Likewise, if interrupts are enabled during suspend then
polling isn't needed.

Furthermore the EGSM (Enter Global Suspend Mode) bit shouldn't be set
in the Command register unless remote wakeup is enabled.  Apparently
some controllers will issue a remote-wakeup interrupt whenever EGSM
is on, even if Resume-Detect interrupts are supposedly disabled.
