usb: composite: Move bitmap related operations to ./include/linux/bitmap.h
The BITMAP related operations can now be moved to ./include/linux/bitmap.h
file to mimic the Linux kernel directory tree.
This change also allows to remove the lin_gadget_compat.h header file
(which is a legacy code only for composite U-boot layer).
It was also possible to remove #includes from several USB gadget drivers.
