Subject: drm/vc4: Remove unecessary dma_fence_ops
Git-commit: 144b09795528780d96491d70619ccbadac324e68
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

dma_fence_default_wait is the default now, same for the trivial
enable_signaling implementation.

v2: Also remove the relase hook, dma_fence_free is the default.
