We don't have two DSI phys defined in sm6125, but if we did both would
presumably have the same compatible string and driver, so the dsiclk
(not the byteclk) should be at index 1 and not at index 0 for dsi1_phy.
This is just the dt-bindings-example, but it is better to keep it
consistent that way for clarity.
