Various minor OHCI tweaks;

    - Fix osdl bugid=2503 by:
	* Change needlessly-scarey message (WARN_ON dumps stack)
	* Tries cleaning up, as if it's just IRQ lossage.

    - Force IRQs off when shutting down a controller that was
      already stopped ... just in case.

    - Allow suspending OHCI during driver initialization, to
      support more aggressive power management.

    - Fix some misleading/wrong debug messages.
