Clearfog: add Helios-4 dtb
Browse files Browse the repository at this point in the history 
The Helios-4 uses the same SoM as the Clearfog and can share all of
the clearfog specific configuration.

The DTB has been copied from the Helios-4 linux fork on github.com:
https://github.com/helios-4/linux-marvell/blob/linux-marvell-4.4/arch/arm/boot/dts/armada-388-helios4.dts
