Add powerhook and shutdownhook to support Notebook. 

Use PAGE_SIZE instead of OHCI_PAGE_SIZE for each DMA mem.
	OHCI_PAGE_SIZE(2kB) will be round up PAGE_SIZE, anyway.
	XXX: need more sophisticated way to manage buffer.
Clear IntEvent first not to lose SelfIDCompleted in multiple bus reset.
Be careful not to clear BusReset int event in SelfID duration to follow
the OHCI spec.
Initiate BusReset if selfid is not completed within 3sec after busreset.
