[PATCH] iommu/arm-smmu: fix module name for parameters

[Li Yang]

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.
