The gem driver will sometimes unmap bus_dma mappings that are still
in use by the hardware. Since the sparc64 has IOMMUs, an access by
the hardware after the unmap operation will cause a fault.
This replaces "disable" calls by "reset" calls. This increases
the time between the command to disable DMA and when the maps
are actually unloaded.
