MLK-17312-5 usb: cdns3: improve the role switch process
Current design tries to switch role no matter it is a dual-role device
or a single-role device. It produces extra switch process, and have an
error message at console when tries to start a non-exist role.
In this commit, we do below changes
- The role switch work queue is only for dual-role or peripheral-only
device.
- For peripheral-only device, we need to switch role to CDNS3_ROLE_END
