Log:
[usb/usbehci]:
- Remove all hardware related structs from usbehci.h as they are now in hardware.h.
- Add debugging routines for usb descriptors, queue heads and transfer descriptors.
- This will break building usbehci, but not a problem as it is not included in the default
build. Will be fixed with later commit.
