spapr_pci: Improve error message
Every PHB must have a unique index. This is checked at realize but when
a duplicate index is detected, an error message mentioning BUIDs is
printed. This doesn't help much, especially since BUID is an internal
concept that is no longer exposed to the user.
Fix the message to mention the index property instead of BUID. As a bonus
print a list of indexes already in use.
