ucm2: Qualcomm: x1e80100: T14s-HiFi: switch DP outputs to dedicated MultiMedia5/6/7 streams

Align UCM with the topology change that added dedicated multimedia
frontends for DisplayPort (commit c8d6762 "ASoC: qcom:
x1e80100-LENOVO-Thinkpad-T14s: add dedicated multimedia frontend for
DisplayPort").

- SectionVerb EnableSequence: enable DISPLAY_PORT_RX_0/1/2 on
  MultiMedia5/6/7 (remove the old MultiMedia1 "0" settings).
- Headphones: disable the DP mixers on the new dedicated streams.
- HDMI0/1/2 devices: route each DISPLAY_PORT_RX_* to its own
  MultiMedia frontend, use dedicated PlaybackPCM "hw:${CardId},4/5/6",
  add explicit PlaybackChannels 2, and keep the existing JackControl.

This gives independent DP audio streams and matches the new topology.
