The data blob apparently does not need to be modified through the fit field of the image_sign_info struct so make it point to const to avoid the need to cast away constness in functions that assign a pointer to const data to the field.
fit_image_setup_verify already had to cast away constness as it assigned a const void * argument to the field. The cast can now be removed.
