Currently we have two conflicting definitions of struct usb_config_descriptor
and struct usb_interface_descriptor in the tree. This is because the USB code
uses additional fields in the structs for internal housekeeping. Add
struct usb_interface and struct struct usb_configuration with the housekeeping
data and embed the corresponding hardware structs into them. This frees the
way to use the definitions from ch9.h in the next step.

Currently we can only (re)scan all USB hosts. Add a function to
scan individual hosts. This is useful for implementing the detect
callback in the next patch.

This renames the USB devices to reflect the bus structure.
The base name for a USB device is usb<devno>. For each child
device we add a -<parent-port-no>. This makes it more easy
to identify devices.

In usb_hub_configure the hub is asked for its descriptor and among other things
its bPwrOn2PwrGood time. In the actual hub_power_on function this information
was not used and a hardcoded value was used instead. For some hubs this delay
is to short. So, use the delay the hub wants.

    ehci: speed up initialization

    According to EHCI specification v1.0, the controller should stabilize
    the power on a port at most 20 ms after the port power bit transition.
    So, we put this setting in the virtual descriptor corresponding field,
    (bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each
    controller initialization/enumeration.
