media: staging: tegra-vde: Fix build error

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

If IOMMU_SUPPORT is not set, and COMPILE_TEST is y,
IOMMU_IOVA may be set to m. So building will fails:

drivers/staging/media/tegra-vde/iommu.o: In function `tegra_vde_iommu_map':
iommu.c:(.text+0x41): undefined reference to `alloc_iova'
iommu.c:(.text+0x56): undefined reference to `__free_iova'

Select IOMMU_IOVA while COMPILE_TEST is set to fix this.
