This patch introduces the support for Keymile's kmcoge4 board which is
the internal reference design for boards based on Freescale's
P2040/P2041 SoCs. This internal reference design is named kmp204x.
The peripherals used on this board are:
- SPI NOR Flash as bootloader medium
- NAND Flash with a ubi partition
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 4 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
CPLD
- 2 I2C busses
- last but not least, the mandatory serial port
The patch also adds a defconfig file for this reference design that is
necessary because of the lowmem option that must be set higher due to
the number of PCIe devices with big ioremapped mem ranges on the boad.

Changes in v4:
- remove the partition layout for the NAND Flash as well as it was
forgotten
- Rebased on top of v3.15-rc1
Changes in v3:
- add the compatible strings for the localbus nodes
- remove the IRQ part of the board-control node as it is currently being
reworked
Changes in v2:
- add some nodes on the localbus CS when possible
- only use the corenet_generic machine and add kmcoge4 to the supported
boards instead of defining a new kmp204x machine
- set better and more precise device nodes for the spi devices
- remove the partion layout for the spi_flash@0
