Connecting to "parent" host controller

USB drivers can now connect to host controller drivers they physically
belong to (so far, everything connected to VHC).

Each USB device must implement the USB interface of libdrv to allow
this (it is absolutely neccesary for hubs).

USB drivers can use usb_drv_hc_connect() to connect to "their" host
controller.

Child devices created with usb_drv_register_child_in_devman()are set
to handle this connection automatically.

UHCI and VHC drivers were updated.
