GKI: lito: Add kgsl-3d0 DT links to force GMU and kgsl-smmu to probe first
If the GMU or kgsl-smmu device probes after the kgsl-3d0 device, then the
GPU will get into a bad state when trying to suspend the GMU. This state
is not recoverable without rebooting the device. Adding these DT links,
forces gmu and kgsl_smmu to probe before msm_gpu.
