usb: xhci: Enable TT to support LS/FS devices behind a HS hub

So far LS/FS devices directly attached to xHC root port can be
successfully enumerated by xHCI driver, but if they are connected
behind a hub, the enumeration process fails to address the device.

It turns out xHCI driver still misses a part that in the device's
input slot context, all Transaction Translator (TT) related fields
are not programmed. The xHCI spec defines how to enable TT.

Now LS/FS devices like USB keyboard/mouse can be enumerated behind
a high speed hub.

There is no way to know whether the attached device is a hub or
not in advance before the device's descriptor is fetched. But
once we know it's a high speed hub, per the xHCI spec, we need
to tell xHC it's a hub device by initializing hub-related fields
in the input slot context.

hub needs to be updated after the hub descriptor is fetched. This
adds a new op that does this.

usb: xhci: Program 'route string' in the input slot context

xHCI spec says: the values of the 'route string' field shall be
initialized by the first 'Address Device' command issued to a
device slot, and shall not be modified by any other command.

So far U-Boot does not program this field, and it does not prevent
SS device directly attached to root port, or HS device behind an HS
hub, from working, due to the fact that 'route string' is used by
the xHC to target SS packets. But in order to enumerate devices
behind an SS hub, this field must be programmed.

With this commit and along with previous commits, now SS & HS devices
attached to a USB 3.0 hub can be enumerated by U-Boot.

As usual, this new feature is only available when DM is on.
