[PATCH v2] ARM: dts: aspeed: Add a palmetto board (AST2400)

[Cédric Le Goater]

Palmettos were the first OpenPOWER systems built by Tyan with the
product name: GN70-BP010. They contained an IBM POWER8 Turismo SCM
processor and an Aspeed AST2400 SoC.

The ast2400_openbmc_defconfig defconfig is based on the evb-ast2400
defconfig, plus these extras :

  CONFIG_BOOTCOMMAND="bootm 20080000"
  CONFIG_DEFAULT_DEVICE_TREE="ast2400-palmetto"
  CONFIG_PHY_NCSI=y

 Changes in v2 :

 - device tree cleanups to match HW
 - renamed defconfig to ast2400_openbmc_defconfig
