[PATCH] USB: OHCI root hub suspend/resume/wakeup

This patch goes on top of the previous two, and the hcd-0506 patch:

  - Moves root hub suspend/resume code out of PCI-specific bus glue
    into generic hub code.  That way it's easy to re-use it even
    for non-PCI implementations like SA1111, OMAP, and LH7A404.
    (Plus, given CONFIG_USB_SUSPEND, it can be invoked with sysfs.)

  - Root hub suspend is a lot more careful, as is root hub resume.
    Pending transactions are now shut down more consistently; and
    more registers are re-initialized on resume.

  - The PCI bus glue is now left with truly generic PCI stuff, plus
    some PMAC-specific stuff (which doesn't include irq disabling
    any more, hcd-0506 moves that up a level in the stack).

  - Remote wakeup support is basically working for the root hub.
    (given CONFIG_USB_SUSPEND to suspend devices and enable it).

  - Idle HCs will now automatically suspend themselves, and resume
    as necessary.  This saves a certain amount of power on most
    systems, and matches what UHCI has been doing for a while.

The large size of this patch is mostly because of moving that
root hub suspend/resume code out of the PCI-specific glue.
