It looks like it's ~4 years since we updated some of these, so do a bulk
update.
Verified that the before and after generated configs are exactly the
same.
Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated
result.

Because powernv arrived after these other platforms, the defconfigs
didn't have PPC_POWERNV disabled, and being default y it gets turned on.
If we're going to bother having defconfigs for the specific platforms
then they should only build the code required for those platforms.
The grab bag of everything config is ppc64_defconfig.

CONFIG_FHANDLE is a requirement for systemd and with the increasing
uptake of systemd within distros it makes sense for 64 bit defconfigs
to include it.

Remove CONFIG_POWER4_ONLY, the option is badly named and only does two
things:
- It wraps the MMU segment table code. With feature fixups there is
little downside to compiling this in.
- It uses the newer mtocrf instruction in various assembly functions.
Instead of making this a compile option just do it at runtime via
a feature fixup.

Now that all EEPROM drivers live in the same place, let's harmonize
their symbol names.
Also fix eeprom's dependencies, it definitely needs sysfs, and is no
longer experimental after many years in the kernel tree.

Turned off CONFIG_PCI_LEGACY and turned on EXT4, and otherwise mostly
took the defaults. This also updates ppc6xx_defconfig, which covers
the 6xx/7xx/7xxx-based embedded boards.

Some machines supported by the maple platform have an Obsidian

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.

Rename MPIC_BROKEN_U3 to something a little more descriptive. Its
effect is to enable support for HT irqs behind the PCI-X/HT bridge on

I think that most people who use maple_defconfig are doing so for a JS21,
so it might make sense to turn Tigon3 support on by default.
Built and booted on a JS21.
