Subject: [PATCH] powerpc/pci: Reduce log level of PCI I/O space warning

From: Benjamin Herrenschmidt <[email-masked]>
Date: Wed, 22 Jun 2016 17:23:07 +1000

If a PHB has no I/O space, there's no need to make it look like
something bad happened, a pr_debug() is plenty enough since this
is the case of all our modern POWER chips.
