arm64: dts: qcom: x1e78100-t14s: Enable fingerprint reader

Browse source

On Lenovo ThinkPad T14s, the fingerprint reader placed in the power
button is connected via the usb_2 controller. The controller has only
a USB 2.0 PHY which is then connected via a NXP PTN3222 eUSB2 repeater,
which in turn is connected to the Goodix fingerprint reader.

So enable all the usb_2 controller and PHY nodes, set dual-role mode to
host and describe the eUSB2 repeater in order to get the fingerprint
reader discovered.
