[PATCH] OHCI PM updates
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?).
