The number of image array entries global variable is required to support EFI capsule update. This information is exposed as a num_image_type_guids variable, but this information should be included in the efi_capsule_update_info structure. This commit adds the num_images member in the efi_capsule_update_info structure. All board files supporting EFI capsule update are updated.
