powerpc/eeh: Fix PE location code
[ Upstream commit 7e56f627768da4e6480986b5145dc3422bc448a5 ]
In eeh_pe_loc_get(), the PE location code is retrieved from the
"ibm,loc-code" property of the device node for the bridge of the
PE's primary bus. It's not correct because the property indicates
the parent PE's location code.
This reads the correct PE location code from "ibm,io-base-loc-code"
or "ibm,slot-location-code" property of PE parent bus's device node.
