The Linksys WRT3200ACM (Rango) is the lates Armada-385 based router in
the Linksys WRT AC Series which got released in October 2016.
The file armada-385-linksys-rango.dts is loosly based off of a DTS
authored by Imre Kaloz.
As Rango is part of the armada-385-linksys family of boards use the
armada-385-linksys.dtsi as basis. As for functional differences to Imre
Kaloz dts, the wlan LEDs aren't connected to the expander chip pca9635
but directly to GPIOs. Then mpp47 controls the USB2.0 port and not the
USB3.0 port, so use the correct GPIO mpp44 for it.
Other changes can be categorized as just cleanup / reorganization due to
using the armada-385-linksys.dtsi.

Notes:
The sdhci node is taken as is, the current node lets one use the
wireless part of the attached sd8887. There is an issue with the
initalization of the bluetooth firmware though. Haven't had the time
to investigate that in depth so far but shouldn't hold up the Rango
addition.
The non-removable property might be more appropriate than broken-cd
though.
Checkpatch complains about the line length of the URL, though not much
room there. Checkpatch also complains about the vendor prefix linksys
not being documented, however this follows the examples given by the
other boards.
