USB: Fix PS3 USB shutdown problems

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)
