99bddfd01e ppc/pnv/pci: Fix PHB xscom registers memory region name
The name is for the region mapping the PHB xscom registers. It was
apparently a bad cut-and-paste from the per-stack pci xscom area just

We are about to allow passing Int128 to/from tcg helper functions,
but libffi doesn't support __int128_t, so use the structure.

In order for atomic128.h to continue working, we must provide
a mechanism to frob between real __int128_t and the structure.
Provide a new union, Int128Alias, for this.  We cannot modify
Int128 itself, as any changed alignment would also break libffi.
