The attached patch allow entering sleep state in the JBT LCM before the
pixel clock is turned off. This was found to be required according to
the partial spec provided by Joerg in bug 1841.

While this patch fixes some white screen issue, it's not very elegant. I
think we should rework the display interface (this was introduce by OM)
to have a more granular way to create interaction between frame buffer
and the LCM. Also, it would be nice if we could hook direct actions on
the backlight to prevent white flash from kernel side wihtout having to
trade on power drain.
