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. Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Stefan Agner <stefan.agner@toradex.com>
