This property is only useful if a node has children as it allows them
to then use io-channel properties in the parent. Here there are no
children.
This is harmless, but we are planning to shortly drop this property
as it is rarely used correctly and there is little reason it would
ever be needed as we can just provide the io-channels property to
any child nodes that need it.

MicroUSB port on OdroidU3+ boards can operate both as peripheral or as
host port. Till now it was configured as pheriperal only port, but it
turned out that the DWC2 driver code already handles everything needed to
support USB role-switch, so switch it to dual-role (OTG) mode. This has
no effect on OdroidU3 (without 'plus') and OdroidX2, which doesn't have
USB needed ID pin and VBUS wiring. Those will still operate correctly in
pheriperal mode only.
