usb_host: support to disable usb controller types

Browse Source 
The commits adds the same configuration values as supported up to now by
the monolithic usb driver. In contrast to the original, by default all drivers
are started. Disabling a controller type is used by Sculpt, e.g. for OHCI if
running Sculpt inside Virtualbox.
