This adds a common board file for almost all of the "simple" PowerPC 44x
boards that exist today.  This is intended to be a single place to add
support for boards that do not differ in platform support from most of the
evaluation boards that are used as reference platforms.  Boards that have
specific requirements or custom hardware setup should still have their own
board.c file.

This changes the cpu_idle loop for 44x platforms to utilize the Wait Enable
feature of the CPU.  This helps virtulization solutions know when the guest
Linux kernel is in an idle state.

A command line option called "idle" is also added to allow people to change
the idle loop back to the original variation.  This is done by setting
"idle=spin" on the kernel command line.

The AMCC 440EP Yosemite board is very similar to the original AMCC Bamboo
board.  This adds a YOSEMITE option to Kconfig, and reuses the existing
bamboo board support in the kernel.

Canyonlands is the AMCC 460EX eval board, featuring nearly all of the 460EX
interfaces:

- 1 * PCI (max 66MHz), 2 * PCIe (one 4-lane, one 1-lane)
- 2 * GBit Ethernet with TCP/IP acceleration
- USB 2.0 Host/Device OTG and Host interface
- SATA port

This adds platform support code for the Ebony (440GP) evaluation
board.  This includes both code in arch/powerpc/platforms/44x for
board initialization, and zImage wrapper code to correctly tweak the
flattened device tree based on information from the firmware.  The
zImage supports both IBM OpenBIOS (aka "treeboot") and old versions of
uboot which don't support a flattened device tree.

This prepares for Ebony/440 support by creating an
arch/powerpc/platforms/44x directory.  It is populated with a single
misc_44x.S file, into which is moved the 44x specific reset code from
head_44x.S (on the grounds that we should really stop clogging up the
head_* files with random asm helper routines).

At the same time, we disable the (empty save Kconfig and Makefile)
arch/powerpc/platforms/4xx directory from the arch/powerpc/platforms
Makefile.  Contrary to the comment in
arch/powerpc/platforms/4xx/Makefile, attempting to build such an empty
Makefile will fail, thus breaking compile for the 44x platforms we're
about to add.  It can go back in once we start porting some of the 40x
platforms (and thus it becomes non-empty).
