powerpc: add an ioremap_phb helper

Factor code shared between pci_64 and electra_cf into a ioremap_pbh helper
that follows the normal ioremap semantics, and returns a useful __iomem
pointer.  Note that it opencodes __ioremap_at as we know from the callers
the slab is available.  Switch pci_64 to also store the result as __iomem
pointer, and unmap the result using iounmap instead of force casting and
using vmalloc APIs.
