Add separate detach callback to USBPortOps, split
uhci/ohci/musb/usbhub attach functions into two.
Move common code to the usb_attach() function, only
the hardware-specific bits remain in the attach/detach
callbacks.
Keep track of the port it is attached to for each usb device.

A bit better documentation of the USB device API, namely

Rewrite of usb_generic_handle_packet() to make it more
reable and easier to follow.
