fix a problem in the c7x0 backlight handling...
Bah! Got confused by the input interval for ODevice::setDisplayBrightness() (once) again - it has been ridiculous to scale that down from [0-255] to the actual interval since the day we invented ODevice::displayBrightnessResolution(). I'm going to remove that antique cruft soon.
