CONFIG_DEVICE_TREE was the only user of CONFIG_WANT_DEVICE_TREE but
it was removed in commit id 2543133381
(bootwrapper: Build multiple cuImages).
This removes CONFIG_WANT_DEVICE_TREE from Kconfig and the defconfigs.

512x is very similar to 83xx and most
of this is patterned after code from 83xx.

Some of the more recent e300 cores have the same performance monitor
implementation as the e500. e300 isn't book-e, so the name isn't
really appropriate. In preparation for e300 support, rename a bunch
of fsl_booke things to say fsl_emb (Freescale Embedded Performance Monitors).

* Allow multiple boards to be selected in a single build
* Removed Kconfig option '83xx' which existed only for compat with arch/ppc
* Removed Kconfig option 'PPC_MPC836x' since its not used
* Renamed Kconfig option 'MPC834x' to 'PPC_MPC834x' to match others
* Added a multiplatform 83xx defconfig (mpc83xx_defconfig).

* 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 adds some basic real mode based early udbg support for 40x
in order to debug things more easily

Currently there's no way to enable early boot console on PowerPC 44x
not specifying uart's physical address in kernel config, which is used
for very early debug messages. This patch splits very early debug output
(which needs uart physical address in kernel config) and early boot console
(which searches for uarts in the device tree using find_legacy_serial_ports).
We enable early boot console for all 44x processors, while (dangerous)
early debug is user-selectable.

Instead of having in the makefile all the option that
requires rheap, we define a configuration symbol
and when needed we make sure it's selected.

Since the PPE on cell is an in-order core, it suffers significantly
from wrong instruction scheduling. This adds a Kconfig option that
enables passing -mtune=cell to gcc in order to generate object
code that runs well on cell.

The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar
to those in the 32 bit general-purpose processors, so it makes sense to
treat them as the same CPU family.
Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the
same.

A lot of the options in arch/powerpc/Kconfig deal with the CPU menu,
and my next patches add more to them. Moving them to a new
arch/powerpc/platforms/Kconfig.cputype file makes it easier to
follow.
There are no functional changes in here.
