marvell: armada385: Add the Turris Omnia board

The Turris Omnia is a open-source router created by CZ.NIC.

The code is based on the Marvell/db-88f6820-gp by Stefan Roese
with modifications from Tomas Hlavacek in the CZ.NIC turris-omnia-uboot
repository, which can be found at
https://gitlab.labs.nic.cz/turris/turris-omnia-uboot

By default, the Turris Omnia uses btrfs as the main and only filesystem,
and also loads kernel and device tree from this filesystem. Since U-Boot
does not yet support btrfs, you should not flash your Turris Omnia board
with this unless you know what you are doing.
