drm/exynos/dma: Drop iommu_dma_init_domain() stub

Browse Source 
Commit 1feda5eb77 ("drm/exynos: Use selected dma_dev default iommu
domain instead of a fake one") removed the code around creating a
custom IOMMU domain, but forgot to remove the stub.

Remove the iommu_dma_init_domain() stub as the function is no longer
referenced, and was also made private to the IOMMU DMA code.
