USB: add do_wakeup parameter for PCI HCD suspend
This patch (as1385) adds a "do_wakeup" parameter to the pci_suspend
method used by PCI-based host controller drivers. ehci-hcd in
particular needs to know whether or not to enable wakeup when
suspending a controller. Although that information is currently
available through device_may_wakeup(), when support is added for
runtime suspend this will no longer be true.
