When a USB device is put into suspend mode, the current drawn from VBUS
has to be less than 500 uA. Some transceivers need to be put into a
special power-saving mode to accomplish this, and won't have a separate
OTG driver handling that.

This adds a suspend method to the "otg_transceiver" struct -- misnamed,
it's not only for OTG -- and calls it from the OMAP UDC driver.

The uhci-hcd driver is fairly lax about the way it handles isochronous
transfers.  This patch (as579) improves it in three respects:

	TDs for a new URB aren't added to the schedule until all of
	them have been allocated.  This way there's no risk of the
	controller executing some of them when an allocation fails.

	TDs for an unlinked URB are removed from the schedule as soon
	as the URB is unlinked, rather than waiting until the URB is
	given back.  This way there's no risk of the controller still
	executing a TD after the URB completes.

	The urb->error_count values are now reported correctly.
	Although since they aren't used in any drivers except for
	debug messages in the system log, probably nobody cares.

This patch (as580) is perhaps the only result from the long discussion I
had with David about his changes to the root-hub suspend/resume code.  It
renames the hub_suspend and hub_resume methods in struct usb_hcd to
bus_suspend and bus_resume.  These are more descriptive names, since the
methods really do suspend or resume an entire USB bus, and less likely to
be confused with the hub_suspend and hub_resume routines in hub.c.

It also takes David's advice about removing the layer of bus glue, where
those methods are called.  And it implements a related change that David
made to the other HCDs but forgot to put into dummy_hcd.

There appears to be one more case where the HP8200 CD writer devices are
detected as flash readers - when the USB cable is replugged after use, with
the power cable still connected.

Oddly enough, the identify device command appears to 'fall through' when the
devices are in this state, the status register reading exactly the same opcode
as the command (0xA1) that was just executed.

I think it's safe to label this behaviour as specific to HP8200 devices, I
can't get the flash devices to respond like this.

This patch should solve the last of the HP8200 issues which have cropped up
recently.

Because there is no bulk_interrupt_message() routine and no
USBDEVFS_INTERRUPT ioctl, people have been forced to abuse the
usb_bulk_message() routine and USBDEVFS_BULK by using them for interrupt
transfers as well as bulk transfers.

This patch (as567) formalizes this practice and adds code to
usb_bulk_message() for detecting when the target is really an interrupt
endpoint.  If it is, the routine submits an interrupt URB (using the
default interval) instead of a bulk URB.  In theory this should help HCDs
that don't like it when people try to mix transfer types, queuing both
periodic and non-periodic types for the same endpoint.

Not fully tested -- I don't have any programs that use USBDEVFS_BULK for
interrupt transfers -- but it compiles okay and normal bulk messages work
as well as before.

The PCI "early usb handoff" quirk logic didn't work like "ohci-hcd" ...
This patch makes it do so by:

  - Resetting the controller after kicking BIOS off, matching the
    normal "chip in hardware reset" startup mode;

  - Reporting any BIOS that borks this simple handoff; it's likely
    got a few other surprises for us too.

  - Ignoring that handoff on HPPA;

The diagnostic string is mostly shared with EHCI, saving a few bytes.

This simplifies the OHCI root hub suspend logic:

 - Uses new usbcore root hub calls to make autosuspend work again:
	* Uses a newish usbcore root hub wakeup mechanism,
	  making requests to khubd not keventd.
	* Uses an even newer sibling suspend hook.

 - Expect someone always made usbcore call ohci_hub_suspend() before bus
   glue fires; and that ohci_hub_resume() is only called after that bus
   glue ran.  Previously, only CONFIG_USB_SUSPEND promised those things.
   (Includes updates to PCI and OMAP bus glue.)

 - Handle a not-noticed-before special case during resume from one of
   the swsusp snapshots when using "usb-handoff":  the controller isn't
   left in RESET state.  (A bug to fix in the usb-handoff code...)

Also cleans up a minor debug printk glitch, and switches an mdelay over
to an msleep (how did that stick around for so long?).
