backlight rework: Condat light driver accepts levels The present change is another intermediate step on the path toward new FreeCalypso backlight handling. At this intermediate step the Condat light driver accepts 0-255 backlight levels driven by MFW, and puts them out on PWL on Luna development boards. At the same time on C139 it is now possible to turn on the display backlight with or without the keypad bl - the lsb of the 0-255 backlight level controls the keypad bl. MFW presently drives only 0 and 255 backlight levels, thus there is no visible behavioral change yet - but the plan for subsequent stages of this backlight rework is to add a dimmed backlight state (no keypad bl on C139) during active calls.
