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.

revisions require the PHY regulator base address, whereas others require the
PHY lane base address. See below for each PHY revision.

* "dsi_phy_regulator"
For DSI 14nm PHY:

2 clocks: A byte clock (index 0), and a pixel clock (index 1).
