This doesn't sound like a correct assumption, especially if you recall how 
common clock framework works - it disables any unclaimed clock 
automatically. Also we might want to support gating from power management 

IMHO you should simply export the dout_hdmi_pixel clock, keeping the 
original sclk_pixel exported as well.
