Odroid XU needs its own dts for sure. I think you can make a copy of
SMDK dts and name it -odroidxu straightaway and work further with it.

exynos5410-pinctrl.dtsi is used for generic SoC-wide pinctrl
definitions, such as pin banks and pin groups. There should be no
board-specific things defined in it. Instead respective board dts should
have them.

The 3D GPU is completely independent from display controllers, which are
standard Samsung IP blocks, so you should be able to get unaccelerated
output using VP+Mixer+HDMI or FIMD+DP using existing drivers.
