These OHCI updates go along with usbcore changes to avoid power_state
(mostly for sysfs) and leave usbcore handling usb_device state (except
for quick-disconnect on STD resume).

 - detect and ignore a root hub status polling call made during
   suspend without USB_RESUME (it'd act like CardBus eject...)

 - detect and ignore a superfluous root hub resume call made in
   some cases with USB_RESUME

 - use irqsave spinlock calls in timer callback paths

 - don't expect usbcore to understand "disconnect the root hub"

 - avoid some pointless delays/faults

So it should fix a lot of the problems folk have been having with
OHCI in the latest 2.6.10-rc1-bk kernels.
