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.

unset CONFIG_PCI_LEGACY in the defconfigs as none of them enable
ISDN drivers which seem to be the only place we are using pci_find_device

Since we are updated defconfigs I went ahead and moved the
asp8347_defconfig under 83xx/ and the mpc8536_ds_defconfig under
85xx/ as that is where they should have been to start with.

The defconfigs for Freescale 85xx and 86xx SOCs had bad choices for some
audio related options.  In particular, OSS emulation should be enabled,
and the old ALSA API should be disabled.

* Allow multiple boards to be selected in a single build
* Removed Kconfig option '85xx' which existed only for compat with arch/ppc
* Added a multiplatform 85xx defconfig (mpc85xx_defconfig). This builds
  all 85xx boards except sbc8560 and stx_gp3 since these to boards have
  board specific ifdef in driver code that may break all other boards

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.

The MPC834x SYS board has always been called the MPC834x MDS since its public
release.  Removed all references to SYS and replaced with MDS.  Additionally
renamed the .dts to match the defconfig (mpc834x_mds*).

Updated MATH_EMULATION depends to be on PPC_MPC832x instead of PPC_83xx.  Only
the the MPC832x has no floating point unit in the core.  Updated the other
83xx defconfigs that got math emulation turned on incorrectly.

This fixes MPC834x MDS (formerly SYS) and ITX platform code to get IRQ data (including PCI) from the device tree, and to use the new IPIC code.

renamed defconfig (sys -> mds), left one redundant NULL assignment in mpc83xx_pcibios_fixup to keep the compiler happy.

MPC834x uses the gianfar network driver which now uses the new phylib.  We
need to update the platform code to create a gianfar platform MDIO bus and
pass the right intializations to the gianfar driver to make things work
again.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
