I don't think there is anything more needed from the Barebox side. At least the same change works for me and gets me a working HDMI display on the EVK board. I don't use the NXP kernel through, but running a 4.20 based kernel with lot of downstream bits ported. This might be a incompatibility of your kernel with the imx8 ATF version shipped with Barebox.
