Commit cd221bd24ff5 ("iommu/arm-smmu: Allow building as a module") introduced a side effect that changed the module name from arm-smmu to arm-smmu-mod. This breaks the users of kernel parameters for the driver (e.g. arm-smmu.disable_bypass). This patch changes the module name for parameters back to arm-smmu to be consistent with older kernel.
