USB: gadget: composite: usb_string_ids_*() functions added
usb_string_ids_tab() and usb_string_ids_n() functions added to
the composite framework. The first accepts an array of
usb_string object and for each registeres a string id and the
second registeres a given number of ids and returns the first.
This may simplify string ids registration since gadgets and
composite functions won't have to call usb_string_id() several
times and each time check for errer status -- all this will be
done with a single call.
