They return the following values. * 1 if qman/bman portals were all probed correctly * 0 if qman/bman portals were not yet probed * -1 if probing of qman/bman portals failed Portals are considered successful probed if no error occurred during the probing of any of the portals and if enough portals were probed to have one available for each cpu. The error handling paths were slightly rearranged in order to fit this new functionality without being too intrusive. Drivers that use qman/bman portal driver services are required to use these APIs before calling any functions exported by these drivers or otherwise they will crash the kernel. First user will be the dpaa1 ethernet driver, coming in a subsequent patch.

Fix this by adding a function that does proper iova -> phys conversions using the iommu api and update the code to use it. Also, a dma_unmap_single() call had to be moved further down the code because iova -> vaddr conversions were required before the unmap. For now only the contiguous frame case is handled and the SG case is split in a following patch. While at it, clean-up a redundant dpaa_bpid2pool() and pass the bp as parameter.
