Select IOMMU_IOVA while COMPILE_TEST is set to fix this.

It should be better to unconditionally select IOMMU_IOVA here.
The same could be done for drivers/staging/media/tegra-vde/ and drivers/gpu/host1x/, please see [1].
Yep, I will repost, thanks!
No need to resend, I already have patches for that.
