[PATCH] powerpc: Enable NUMA balancing in pseries[_le]_defconfig

[Michael Neuling]

This enables NUMA balancing in pseries[_le]_defconfig.

NUMA balancing can do some nasty things with the low level mm code and
has been causing some issues with the cxl driver.  Also distros are
enabling it (eg Ubuntu), so it would be good to get some more test
coverage with it.

mpe: This might help us find some bugs in v3.18, but it's probably
     better suited for your next tree.
