This patch adds devm_of_platform_populate() calling to populate
the rcar-usb3-role-switch driver.
For now, this renesas_usb3 driver doesn't use any APIs of
the usb role switch framework because the usb_role_switch_get()
API depends on the device_connection framework and this framework
is not good match on device tree environment. However, the select
USB_ROLE_SWITCH needs to enable the rcar-usb3-role-switch driver.
