[PATCH v3 2/2] ARM: dts: add support for Turris Omnia

This machine is an open hardware router by cz.nic driven by a
Marvell Armada 385.

Changes since (implicit) v1:

  - disable rtc
  - change compatible to "cznic,turris-omnia"

Changes since v2:

 - fix comment for usb at 58000
 - add gpio-expander that serves SPF and phy irq

I kept all three eth devices to keep the ethernet names when users upgrade.
Tomas said that he had problems with the emmc when operating it in DDR50
mode. I didn't see any I/O errors so far and didn't find a way to
limit the device to SDR50 via dt.

IMHO even with some peripherals still missing (SFP, switch, wlan) it
would be the right thing to take this patch as a base to get the
remaining bits sorted. Is it still possible to get it into 4.10?

Best regards
Uwe
