[PATCH 3/3] mach-imx: Kconfig: add option for image with dcd auth block

[Sascha Hauer <s.hauer@pengutronix.de>]

From: Matthias Zoechmann <matthias.zoechmann@ife-doors.com>

Add option CONFIG_HABV4_IMAGE_SIGNED_USB_DCD to select build of barebox
image for i.mx6 devices with an additional authentication block in CSF
("0x0091000 offset size filename").
Additional the barebox toolchain will build now a signed image e.g.
barebox-image-name-dcdus.img for usb loading with SDP DCD_WRITE ROM
command.
