Board specific defconfigs are useful, however with the ability to do
multi-board defconfigs they aren't needed in the top level configs directory.
Move the 4xx board specific defconfigs to individual directories under
arch/powerpc/configs.

Update the 4xx defconfigs to remove WANT_DEVICE_TREE and add MTD_OF_PARTS
where appropriate.

Somehow the EMAC support was dropped (or never really added) to the
Kilauea defconfig file. This patch finally adds EMAC support.

Enable PCI support for these eval boards among other things. Also selects
PCI for Rainier in the Kconfig file.

This updates all the defconfigs in arch/powerpc/configs except iseries
and ps3, which were updated by the preceding commits.
This mostly takes the defaults, except that I turned on tickless idle
and high-resolution timers for everything, and turned off instrumentation
support and "Fair group CPU scheduler" for the smaller/embedded platforms.

When checking out the new NO_HZ support in powerpc, I noticed we never
slept for more than 2 seconds. It turns out SLAB has a 2 second per cpu
timer that causes this.
After switching to SLUB I see some nice 4 second sleeps which is the
limit on this POWER6 box (the decrementer ticks at 512MHz):
slept 4.19 sec
slept 4.19 sec
slept 4.19 sec
slept 4.19 sec
slept 3.96 sec
slept 3.80 sec
slept 2.99 sec
Since SLUB is now the default and some powerpc defconfigs already enable
it, lets enable SLUB across the board for consistency. While doing this
I also noticed that the maple defconfig has SLAB debugging enabled which
is sure to make your box nice and slow. Fix that too.
