    When IOMMU_IOVA is not built-in but host1x is, we get a link error:
    
    drivers/gpu/host1x/dev.o: In function `host1x_remove':
    dev.c:(.text.host1x_remove+0x50): undefined reference to `put_iova_domain'

    drivers/gpu/host1x/cdma.o: In function `host1x_cdma_deinit':

    This adds the same select statement that we have for drm_tegra.
