mvebu: add support for ipTIME NAS1dual

ipTIME NAS1dual is a 1-bay NAS, based on Marvell Armada 385 SoC.

Specifications:
* SoC: 88F6820
* RAM: 2 GiB
* Flash: SPI NOR 64 MiB
* SATA: 1x 3Gb/s
* Ethernet: 2x 1GbE
* USB: 1x 3.0
* Fan: 2 speed level
* UART: J11 (115200 8N1)
  * Pinout: [3V3] (TXD) (RXD) (GND)

Installation via web interface:
1.  Flash **initramfs** image through the stock web interface.
2.  Boot into OpenWrt and perform sysupgrade with sysupgrade image.

Revert to stock firmware:
1.  Perform sysupgrade with stock image.
