powerpc/powernv/pci: Add helper to check if a PE has a single vendor Add a helper that determines if all the devices contained in a given PE are all from the same vendor or not. This can be useful in determining if it's okay to make PE-wide changes that may be suitable for some devices but not for others. This is used later in the series.
