Subject: [PATCH 05/15] [POWERPC] Remove bus_offset in places its not really used

From: Kumar Gala <[email-masked]>
Date: Tue, 26 Jun 2007 20:16:35 -0500

The user of the fsl_pcie code doesn't set bus_offset and 82xx doesn't
require it either.  Remove the places in the code that reference it so
we can remove it all together.
