The DU driver uses the rcar_lvds_clk_enable() and rcar_lvds_clk_disable() functions enable or disable the pixel clock generated by the LVDS encoder, as it requires that clock for proper DU operation. Rename the functions by replacing "clk" with "pclk" to make it clearer that they related to the pixel clock.
