[PATCH 13/26] hw/usb/desc: Reduce some declarations scope

[Philippe Mathieu-Daudé <f4bug@xxxxxxxxx>]

USBDescString is forward-declared. Only bus.c uses the
usb_device_get_product_desc() and usb_device_get_usb_desc()
function. Move all that to the "desc.h" header to reduce
the big "hw/usb.h" header a bit.
