[USBEHCI_NEW]
- Implement CHCDController::Initialize, CHCDController::HandlePnp for PDO / FDO, - Partly implement CHCDController::HandleDeviceControl - Based on mjmartin usbehci sources - Driver now startups and acquires pnp resources - Fails in HandleDeviceControl with IOCTL_GET_HCD_DRIVERKEY_NAME when usbview is launched - Tested in Windows XP SP2 + Vmware Server 2.0.2 svn path=/branches/usb-bringup/; revision=51343
