arm64: dts: qcom: x1e78100-t14s: Enable support for both Type-A USB ports

Browse Source 
The Thinkpad T14s has 2 USB-A ports, both connected to the USB
multiport controller, each one via a separate NXP PTN3222 eUSB2-to-USB2
redriver to the eUSB2 PHY for High-Speed support, with a dedicated QMP
PHY for SuperSpeed support.

Describe each redriver and then enable each pair of PHYs and the
USB controller itself, in order to enable support for the 2 USB-A ports.
