In current NHLT table the device type of all SSP endpoints are set to BT Sideband(0) instead of SSP Analog Codec(4) and the direction only supports Render(0) and Capture(1). Here we introduce two new quirks from topology to set the device type correctly and support two more directions: Render with loopback(2) and Feedback for render(3) for speakers with echo reference or IV sense feedback.
