The mass storage composite function is now compiled in only when CONFIG_USB_GADGET_MASS_STORAGE is defined. Such change provides binary size reduction for boards which use USB download gadget (like am335x_evm) with DFU, but don't use UMS. For example at am335x_evm board reduction is more than 2KiB for text and around 120B for data. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de>
