powerpc/cell: Fixed IOMMU mapping uses weak ordering for a pcie endpoint
At the moment the fixed mapping is by default strongly ordered (the iommu_fixed=weak boot option must be used to make the fixed mapping weakly ordered). If we're on a setup where the southbridge is being used in endpoint mode (triblade and CAB boards) the default should be a weakly ordered fixed mapping. This adds a check so that if a node of type pcie-endpoint can be found in the device tree the fixed mapping is set to be weak by default (but can be overridden using iommu_fixed=strong).
