drm/i915/dp_mst: Disable Panel Replay
Disable Panel Replay on MST links until it's properly implemented. For
instance the required VSC SDP is not programmed on MST and FEC is not
enabled if Panel Replay is enabled.
Fixes: 3257e55d3ea7 ("drm/i915/panelreplay: enable/disable panel replay")
Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/15174
