[POWERPC] Fix for via-pmu based backlight control
This fixes a few issues with via-pmu based backlight control. First, it fixes a sign problem with the setup of the backlight curve since the `range' value there -can- (and will) go negative. Then, it reworks the interaction between this and the via-pmu sleep code to properly restore backlight on wakeup from sleep.
