This patch introduces 'bind_deactivated' flag in struct usb_function.
Functions which don't want to be activated automatically after bind should
set this flag, and when they start to be ready to work they should call
usb_function_activate().
When USB function sets 'bind_deactivated' flag, initial deactivation
counter is incremented automatically, so there is no need to call
usb_function_deactivate() in function bind.
