[U-Boot] [PATCH 3/4 v4] arm: add support for the suen3_p1a board from keymile

[Heiko Schocher]

This patch adds support for the Keymile suen3_p1a board which
is based on the Marvell Kirkwood (88F6281) SoC. As this
is a variant of the mgcoge2_arm_p1a board, this board
also uses common code stored in board/keymile/km_arm/km_arm.c

- changes since v1:
  added comments from Wolfgang Denk:
  get rid of flash_info_t define in board config
  (to get this working patch 1/2 is introduced/needed)

- changes since v2:
  added comments from Wolfgang Denk
  - rearranged if/else in do_spi_toggle()
  - added I/O accessor functions for bootcounter

- changes since v3:
  added comment Scott Wood
  - removed nand_init in do_spi_toggle()

  added comments from Prafulla Wadagaskar
  - km-arm.h renamed to km_arm.h
  - reworked eeprom_write_enable() (deleted it)
    (when reviewing this function, it cropped up, that
     this pin is connected through a gpio pin, not as
     in previous version, through the boco (a FPGA))
  - moved set_sda(), set_scl(), get_sda(), get_scl()
    to km_arm.c
  - split patch in 4 patches (for each board an extra patch)
  - renamed sdramregs.txt in kwbimage.cfg, also license
    info added.
