[PATCH] ppc64: fix iommu cleanup regression
In the recent IOMMU cleanup, the new LPAR code assumes that all PHBs must have a dma window assigned to it. On some machines we don't have a window assinged unless there's an adapter in the slot. In other words, a PHB without a ibm,dma-window property is not a bug and must be tolerated. This patch fixes that, and also removes a redundant check for the dma-window being defined.
