This is a step backwards. There should be no need to have every driver
have a full struct device associated with it, so removing the
requirement to have a struct device is the right thing to do (and this
patch undoes that).

Sticking to the strict driver model on all display IP on SoCs is
making things overly complicated. Sean is clearly moving the Exynos
DRM in the right direction with his restructuring, so please don't
undo his work like this. Especially not without cc:ing him on the
patches.
