arm64: dts: qcom: x1p42100-lenovo-thinkbook-16: add hdmi bridge with enable pin

Browse Source 
Add TLMM 120 for hdmi bridge enable.
In general this is the same setup as on the T14s. Since its using simple-bridge
and also is Lenovo, we also use the same realtek,rtd2171 compatible.
The real chip identity is not known yet. The bridge is wired with un-swapped
lanes, though.
