[PATCH] iommu/vt-d: No need to export dmar_platform_optin()

[PATCH] iommu/vt-d: No need to export dmar_platform_optin()

[Mika Westerberg]

This function is not called anymore outside of this driver so we can
drop the export and move the declaration to the driver private header.

No functional changes.
