Hi Dmitry,

HW supports OTG mode as well on the USB0 port but for enabling OTG
mode , it requires two things, one is role switch support and another
is VBUS supply on/off support. Both will be taken care of by Type-C
manager HD3SS3220. Currently, VBUS enablement support is not present
in the driver. Once that support is added, I will add OTG support for
the USB0 port, until then we would like to keep it in peripheral mode
for ADB support.

This is the same change which was discussed for lemans-evk [1] applies
for monaco-evk as well.
