ZynqMP USB 3.0 controller OTG (On The Go) mode

I have a bit of confusion with OTG info in Zynq Ultrascale MPSOC Linux USB device driver Xilinx Wiki page.

At beginning at "Missing Features, Known Issues and Limitations" it say:

ZynqMP USB 3.0 controller doesn't support USB 3.0 OTG (On The Go) host/device selection

Near bottom of the same Xilinx Wiki page is OTG Mode procedure description for ZCU102, describing how to set and test OTG mode on ZCU102 with USB 3.0 ports. ZCU102 is ZynqMP.

Post by @ottob in this forum message say: "Xilinx is working on a fix for it so hopefully this will be fixed in 2018.3".

We are designing a ZynqMP board with Xilinx 2018.2 tools and would like to have Host and Device USB 3.0 feature.

From @ottob post I guess we have to instantiate 2x PS USB 3.0 controllers, one to work in Host mode and the other as Device.
