dt-bindings: display: msm/dsi: Add compatible for 14nm DSI PHY
Add the compatible string for 14nm DSI PHY (used in MSM8996/APQ8096). >From 14nm PHY onwards, the "dsi_phy_regulator" reg-name is not required, but "dsi_phy_lane" reg-name is. Update the doc to specify the reg-names each PHY revision needs.
