This patch removes some ft_board_setup() functions from some 4xx boards.
This can be done since we now have a default weak implementation for this
in cpu/ppc4xx/fdt.c. Only board in need for a different/custom
implementation like canyonlands need their own version.

This patch adds the first files for the new esd PMC440 boards.
The next two patches will complete the PMC440 board support.

This patch update the 4xx fdt support. It enabled fdt booting
on the AMCC Kilauea and Sequoia for now. More can follow later
quite easily.

The BCSR status bit for the 66MHz PCI operation was correctly
addressed (MSB/LSB problem). Now the correct currently setup
PCI frequency is displayed upon bootup.
This patch also fixes this problem on Rainier & Yellowstone, since these
boards use the same souce code as Sequoia & Yosemite do.

This patch removes the CFG_PCI_PRE_INIT option completely, since
it's not needed anymore with the patch from Matthias Fuchs with
the "weak" pci_pre_init() implementation.

This patch undoes the patch by Jeff Mann with commit-id ada4697d. As
suggested by AMCC it is not recommended to dynamically change the EBC
speed after bootup. So we undo this change to be on the safe side.

Because the Sequoia board does not boot with an EBC faster than 66MHz,
the clock divider are changed after the initial boot process.
This allows for maximum clocking speeds to be achieved on newer boards.
Sequoia boards with 666.66 MHz processors require that the EBC divider
be set to 3 in order to start the initial boot process at a slower EBC
speed. After the initial boot process, the divider can be set back to 2,
which will cause the boards to run at 83.333MHz. This is backward
compatible with boards with 533.33 MHz processors, as these boards will
already be set with an EBC divider of 2.

- Add support for PPC440EPx & PPC440GRx
- Add support for PPC440EP(x)/GR(x) NAND controller
in cpu/ppc4xx directory
- Add NAND boot functionality for Sequoia board,
please see doc/README.nand-boot-ppc440 for details
- This Sequoia NAND image doesn't support environment
in NAND for now. This will be added in a short while.

- Changed GPIO setup to enable another address line in order to
address 64M of FLASH.
- Added function sdram_tr1_set to auto calculate the tr1 value for
the DDR.

On PPC44x platforms, the startup message generated in "cpu.c" only
comprised the ppc type and revision but not additional informations
like speed etc. Those speed infos where printed in the board specific
code. This new implementation now prints all CPU infos in the common
cpu specific code. No board specific code is needed anymore and
therefore removed from all current 44x implementations.
