If IOMMU_SUPPORT is not set, but IOMMU_IOVA is m and
COMPILE_TEST is y, building fails:
drivers/gpu/host1x/dev.o: In function `host1x_remove':
dev.c:(.text+0x624): undefined reference to `put_iova_domain'
dev.c:(.text+0x624): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `put_iova_domain'
dev.c:(.text+0x62c): undefined reference to `iova_cache_put'
dev.c:(.text+0x62c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `iova_cache_put'
Select IOMMU_IOVA while COMPILE_TEST is set to fix this.
