omap: iommu: remove unused exported API
Remove unused public APIs from OMAP's iommu driver. IOMMU functionality should be exposed only via the generic IOMMU API; this way drivers stay generic, and different IOMMU drivers don't need to duplicate similar functionalities. The rest of the API still exposed by OMAP's iommu will be evaluated and eventually either added to the generic IOMMU API (if relevant), or completely removed. The intention is that OMAP's iommu driver will eventually not expose any public API.
