[PATCH] phy: tegra: xusb: Default otg mode to peripheral

[Aaron Kling via B4 Relay <devnull+webgeek1234.gmail.com@kernel.org>]

From: Aaron Kling <webgeek1234@gmail.com>

Currently, if usb-role-switch is set and role-switch-default-mode is
not, a xusb port will be inoperable until that port is hotplugged,
because the driver defaults to role none. Instead of requiring all
devices to set the default mode, assume that the port is primarily
intended for use in device mode. This assumption already has precedence
in the synopsys dwc3 driver.
