Bug description:
  [Impact] 
   * The fix for bug #1308515 prevents rotation from being used.
   * Rotation support should be added to the intel driver to maintain feature parity when optimus is used vs when not in use.

  [Test Case]
   * Run xrandr --output SOMEOUTPUT --rotation left
      - Expected: Screen should rotate.
      - Bad behavior: Succeeds, but causes a black screen. OR the call fails, and screen is not rotated.

  [Regression Potential] 
   * Will probably regress when modesetting is used, a separate patch might be needed to disable transforms on modesetting. Will have to be tested.
