[PATCH] powerpc: Fix database regression due to scheduler changes

PowerPC's NUMA domain doesn't currently set up some of the newer
sched-domains parameters.

Brian Twichell <tbrian@us.ibm.com> discovered and diagnosed a 1.5% OLTP
database regression on a 4 core POWER5 system that was due to the use of
NUMA scheduling on ppc64.

This patch applies some saneish values to the parameters, in line with
other architectures. This solves the regression.
