usb: gadget: move usb_gadget_controller_number() into a .c file and libcomposite
After I moved the function from the header file to the c file I see:
| $ size drivers/usb/gadget/gadget_chips.o
| text data bss dec hex filename
| 1048 0 0 1048 418 drivers/usb/gadget/gadget_chips.o
That is almost a KiB which is removed from each user.
As Felipe pointed out, the function / usage is very dumb actually. This is
used for the following reasons:
- epautoconf ep hint (could provide a per-gadget callback)
- miss-features. currently the missing altsetting on pxa's and something
ZLP related on musbhdrc (looks like an optimisation which could be
implemented in musb itself if it is correct)
- unique BCD accross all UDCs. Not sure how important this is.
