Subject: 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.
