Add the retimer for usb_1_ss0 port (USB0), in order to enable
super-speed enumeration on that port.

Stray \n, but you should really have a @2 port here as well.

Can we ad port@2 and leave it empty?

Why would you? Just connect it to port2 of the connector under pmic-glink

Because the port@2 of pmic-glink (pmic_glink_ss0_sbu) is already
connected to usb-1-ss0-sbu-mux (onn,fsusb42). This is different compared
to other connectors.

Are both the SBU mux and the Parade retimer present on board?
The former is redundant since the retimer already has a superset of its
functionality, so that sounds rather odd.

fsusb42 might be also used to switch SBU lines for other purposes (e.g.
for the debug).

Currently while connecting super-speed devices to the usb_1_ss0
(USB0 port), it falls back to high-speed. Add the retimer for
USB0 port, enabling super-speed enumeration on that port.
