When the hdmiphy clock is configured with the same pixel clock rate using clk_set_rate() the clock framework do not signal the hdmi phy driver to set_rate when switching between 8-bit and Deep Color. This result in pre/post pll not being re-configured when switching between regular 8-bit and Deep Color video formats. Fix this by calling set_rate in power_on to force pre pll re-configuration.
