Subject: ARM: dts: am57xx-idk: Put USB2 port in peripheral mode

[ Upstream commit 5acd016c88937be3667ba4e6b60f0f74455b5e80 ]

USB2 port can be operated in dual-role mode but till we have dual-role support in dwc3 driver let's limit this port to peripheral mode.

If we don't do so it defaults to host mode. USB1 port is meant for host only operation and we don't want both ports in host only mode.
