[PATCH 1/2] gen-dtb-s: reference OF IMD entries automatically

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We currently require IMD_OF_USED to get the DT compatible into the
barebox image data meta section. As the PBL is already referencing the
DT to pass it along to barebox proper, let's add a reference from the DT
to the image data section to make IMD_OF_USED unnecessary.
