kirkwood: add support for Ctera C200 V1 NAS

2-Bay NAS - maximum two 3.5" Harddisks

Hardware:
  - SoC: Marvell 88F6281-A1 ARMv5TE Processor 1.2GHz
  - Ram: 512MB (4x Nanya NT5TU128M8GE-AC)
  - NAND Flash: 256MB (Samsung 216 K9F2G08U0C)
  - Lan: 1x GBE (Marvell 88E1116R-NNC1)
  - Storage: 2x SATA HDD 3.5" Slot
  - USB: 2x USB 2.0 port
  - Console: Internal J3 connector (1: Vcc, 2: Rx, 3: Tx, 4: GND)
  - LEDs: 13x GPIO controlled
  - Buttons: 2x GPIO controlled

Known issues:
  - Buzzer is unused due lack of proper driver

Installation:
  - Apply factory initramfs image via stock web-gui.
  - Do sysupgrade to make installation complete.

Back to stock:
  - OpenWrt rootfs partition use unused space after stock firmware.
  - Full revert is possible.
  - Login via ssh and run: ctera_c200-v1_back_to_factory
