Brings EP405 support to arch/powerpc. The IRQ routing for the CPLD
comes from a device-tree property, PCI is working to the point where
I can see the video card, USB device, and south bridge.
This should work with both EP405 and EP405PC.
I've not totally figured out how IRQs are wired on this hardware
though, thus at this stage, expect only USB interrupts working,
pretty much the same as what arch/ppc did.
Also, the flash, nvram, rtc and temp control still have to be wired.

Currently it's impossible to build a ps3_defconfig which will reboot
without modules installed. This makes it all too easy to find yourself
with a PS3 that won't reboot.
This is because the system manager driver, which provides the reboot
mechanism, is only selectable if PS3_ADVANCED is set, else it defaults
to m. In ps3_defconfig PS3_ADVANCED is not set, therefore the system
manager is built as a module.
It would be desirable IMHO for the defconfig to produce a kernel that
boots and reboots, without needing modules to be installed.

Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop
the serial console from being suspended when the rest of the machine goes
to sleep. This is incredibly useful for debugging power management-related
things; however, having it as a compile-time option has proved to be
incredibly inconvenient for us (OLPC). There are plenty of times that we
want serial console to not suspend, but for the most part we'd like serial
console to be suspended.
This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel
boot parameter (no_console_suspend). By default, the serial console will
be suspended along with the rest of the system; by passing
'no_console_suspend' to the kernel during boot, serial console will remain
alive during suspend.
For now, this is pretty serial console specific; further fixes could be
applied to make this work for things like netconsole.

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.

Specifically it:

to record the correct address for the flash in the device tree based
on the board switches as reported via an FPGA register.
- Prohibits building the old hard-coded "Ebony" flash map on
arch/powerpc kernels, in favour of using physmap_of's device tree
based approach.
- Enables MTD and physmap_of in the Ebony defconfig.
