Subject: [PATCH] arm64: tegra: smaug: Add usb-role-switch support

[ Upstream commit dfa93788dd8b2f9c59adf45ecf592082b1847b7b ]

The USB2 port on Smaug is configured for OTG operation but lacked the
required 'usb-role-switch' property, leading to a failed probe and a
non-functioning USB port. Add the property along with setting the default
role to host.
