      The problem is that currently none of the clocks are being registered for
      OMAP4470 devices and so on boot-up no clocks can be found and the kernel panics.
      
      This fix allows the kernel to boot without failure using a simple RAMDISK file
      system on OMAP4470 blaze board.
      
      Per feedback from Paul and Benoit the 4470 clock data is incomplete for new
      modules such as the 2D graphics block that has been added to the 4470.
      Therefore add a warning to indicate that the clock data is incomplete.
