DSI_LANE_CTRL provides bitfield CLKLN_HS_FORCE_REQUEST that forces the DSI clock lane to always enter HS mode.
This is needed by some DSI peripherals which rely on the DSI clock lane as their clock source. If the clock lane transitions between different states, it can disrupt the functioning of such peripherals.
