usb gadget: don't save bind callback in struct usb_gadget_driver
To accomplish this the function to register a gadget driver takes the bind function as a second argument. To make things clearer rename the function to resemble platform_driver_probe. This fixes many section mismatches like WARNING: drivers/usb/gadget/g_printer.o(.data+0xc): Section mismatch in reference from the variable printer_driver to the function .init.text:printer_bind() The variable printer_driver references the function __init printer_bind() All callers are fixed.
