DisplayColor: Properly handle a minValue

* Previously setting anything as a minValue would cause the
  percentages to get out of whack. For instance, setting it to 35
  would cause the maximum percentage to climb above 100% as well
  as still allowing the value to be set lower than the min.
* This makes the maximum for the slider the max value minus the min
  (so we get the proper spread for min to max) and then adds the min
  back on before setting so we can't possibly go below the min.

Cleanup.

Now that button and keyboard backlight don't use the HW framework
anymore, there's no point in having an abstraction for a single use case.

PS2: Remove Vibrator options we already have it and derp in androidmanifest

PS3: Good old whitespace

PS4: remove leftover file and move display options so they fit better
