Add ehci_shutdown() or ohci_shutdown() calls to the USB
PS3 bus glue. ehci_shutdown() and ohci_shutdown() do some
controller specific cleanups not done by usb_remove_hcd().
Fixes errors on shutdown or reboot similar to these:
ps3-ehci-driver sb_07: HC died; cleaning up
irq 51: nobody cared (try booting with the "irqpoll" option)

This patch (as1096) fixes an annoying problem: When a full-speed or
low-speed device is plugged into an EHCI controller, it fails to
enumerate at high speed and then is handed over to the companion
controller. But usbcore logs a misleading and unwanted error message
when the high-speed enumeration fails.
The patch adds a new HCD method, port_handed_over, which asks whether
a port has been handed over to a companion controller. If it has, the
error message is suppressed.

power.power_state is scheduled for removal. This patch (as1053)
removes all uses of that field from drivers/usb. Almost all of them
were write-only, the most significant exceptions being sl811-hcd.c and
u132-hcd.c.
Part of this patch was written by Pavel Machek.

It is not necessary to powerdown the ports on ehci_pci_reinit() when the
chip reset already did that. Removing this saves 20ms during restart
after poweroff paths (which OLPC uses a lot).
To ensure driver startup then behaves consistently, force a reset during
driver startup. (Not doing this was an accident of some previous changes
to the init sequence.)
Make the corresponding change in the PS3 support. It's not clear what
ehci-fsl should do here; it has similar code to the PS3.

dev_dbg() will check format string for you in dummy case also, so remove
buggers.
