[usb/usbehci]
- Initial implementation of usbehci, aka USB 2.0.
- Implement AddDevice, StartDevice, InterruptService and DPC Routines.
- Implement basic IRP queuing and handling.
- Implement starting, stopping of EHCI controller and querying port capabilities.
- Implement PNP for Query Relations, Query ID, Query BusInfo.
- Implement finding the active ports when USB devices are attached and releasing control
to companion controller if devices is not a high speed devices.
- Implement reporting devices connects to upper Pdo (hub) driver.
- Hub driver attaches successfully and sends URBs to query descriptors from USB devices on
Windows.
- Currently not build enabled as it will cause problems with current UsbDriver in trunk.
- Code heavily based on current PCI drivers and UsbDriver from trunk.
