Instead of tweaking a TCE table device by adding there a bypass flag, let's add an alias to RAM and IOMMU memory region, and enable/disable those according to the selected bypass mode. This way IOMMU memory region can have size of the actual window rather than ram_size which is essential for upcoming DDW support. This moves bypass logic to VIO layer and keeps @bypass flag in TCE table for migration compatibility only. This replaces spapr_tce_set_bypass() calls with explicit assignment to avoid confusion as the function could do something more that just syncing the @bypass flag. This adds a pointer to VIO device into the sPAPRTCETable struct to provide the sPAPRTCETable device a way to update bypass mode for the VIO device.
