The various clut handling functions like a setup consistent with the x-screen color depth. Otherwise we observe improper sampling in the gamma tables at depth 30.

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3...
