[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.
