drivers: misc: Fix the argument of iommu_map() for Linux v6.3

Browse Source 
There is additional argument added in iommu_map() from Linux v6.3.
Pass the proper argument from the driver who are using this
APIs. Using conftest methods for differentiating whether
additional argument is needed or not.
