usb: gadget: push VID/PID/USB BCD module option into gadgets
This patch moves the module options idVendor, idProduct and bcdDevice
from composite.c into each gadgets. This ensures compatibility with
current gadgets and removes the global variable which brings me step
closer towards composite.c in libcomposite
