The MODULE_IMPORT_NS macro adds a namespace tag to the module
information. The DMA_BUF namespace is required for Linux v5.16+ kernels
for drivers that use DMA BUF, there is no reason not to populate this
for earlier kernels. Furthermore, some 3rd party kernels prior to v5.16
may require this too and so drop the version check around the DMA BUF
namespace.

Fix build errors when this driver compiled against K6.1 (kernel-oot)
- Remove dma-iommu.h header inclusion as its not present in K6.1
- Define IOVA_RANGE_CACHE_MAX_SIZE if this macro is not defined
- Import DMA_BUF "MODULE_IMPORT_NS(DMA_BUF);" to avoid below error
"ERROR: modpost: module nvscic2c-pcie-epc uses symbol dma_buf_* from
namespace DMA_BUF, but does not import it"

nvscic2c enables xfer between two SoC connected over PCIe.
nvscic2c already available with K5.10
Major changes in nvscic2c-pcie for K5.15:
Integrate with upstream PCIe endpoint function changes.
Allocate new IOVA domain to be used for
empty IOVA allocation.
This IOVA range would be used in iommu_map() to map
physical backing with IOMMU domain attached in PCIe device.
Migrate from nvhost to host1x and tegra-drm interfaces.
