nwze370: improve lcd & backlight

Browse source 
Added lcd inversion
Fix issue where backlight would turn on before first frame rendered
Fix issue where backlight would shortly appear at 100% before PWM is
ready during fade in
Turn off backlight before booting/RoLo/shutdown to avoid it being
enabled on next boot
Fix issue where fade in isn't smooth because brightness levels below 13 were
basically equalivent to off, by removing these brightness levels
