[POWERPC] Fix large hash table allocation on Cell blades
My recent hack to allocate the hash table under 1GB on cell was poorly tested, *cough*. It turns out on blades with large amounts of memory we fail to allocate the hash table at all. This is because RTAS has been instantiated just below 768MB, and 0-x MB are used by the kernel, leaving no areas that are both large enough and also naturally-aligned. For the cell IOMMU hack the page tables must be under 2GB, so use that as the limit instead. This has been tested on real hardware and boots happily.
