[PATCH v2 0/3] arm64: dts: qcom: kodiak: Enable 4-lane DP via QMP Combo PHY

[Mahadevan P]

This series enables full 4-lane DisplayPort operation on SC7280/kodiak
platforms by wiring up the QMP Combo PHY correctly and consolidating
the DP endpoint configuration in the SoC dtsi.

Patch 1 adds mode-switch to the QMP Combo PHY node in kodiak.dtsi,
which is required for the PHY to respond to USB-C Alternate Mode
negotiation and switch into 4-lane DP configuration.

Patch 2 moves the data-lanes property from individual board files into
kodiak.dtsi since the PHY-to-controller wiring is fixed in silicon.
It also removes redundant remote-endpoint and orientation-switch
overrides from qcs6490-rb3gen2 and qcs6490-thundercomm-rubikpi3 that
are already covered by the SoC dtsi.

Patch 3 updates data-lanes from <0 1> to <0 1 2 3> in kodiak.dtsi now
that mode-switch is in place, enabling the full 4-lane DP link.

Changes in v2:
- Split single patch into 3 patches.
- Move mode-switch and data-lanes to kodiak.dtsi instead of board
  file (Neil Armstrong, Konrad Dybcio)
- Remove redundant board-level endpoint and orientation-switch
  overrides now covered by kodiak.dtsi
- v1 received a Reviewed-by from Dmitry on the combined change;
  that tag has been dropped pending re-review of the split.
