Subject: [RFC PATCH 26/35] powerpc: Change PCIBIOS_SUCCESSFUL to 0

From: "Saheed O. Bolarinwa" <[email-masked]>
Date: Mon, 13 Jul 2020 14:22:38 +0200

In reference to the PCI spec (Chapter 2), PCIBIOS* is an x86 concept.
Their scope should be limited within arch/x86.

Change all PCIBIOS_SUCCESSFUL to 0
