gpu: host1x: Set DMA ops on device creation
Currently host1x-instanciated devices have their dma_ops left to NULL,
which makes any DMA operation (like buffer import) on ARM64 fallback
to the dummy_dma_ops and fail with an error.
This patch calls of_dma_configure() with the host1x node when creating
such a device, so the proper DMA operations are set.
