The GPU subsystem node was a workaround to have a central device to bind V3D and display to. Following the lead of 246774d17fc0 ("drm/etnaviv: remove the need for a gpu-subsystem DT node"), remove the subsystem node usage and just create a platform device for the DRM device to attach to if any of the subsystem devices are present.
v2: Simplify the DT walking code. v3: Always put the node.
