Devicetrees may specify the rotation at which the camera is
mounted in the hardware. If available, this gets populated in camera 
properties. Rotate the viewfinder output accordingly in qcam qt and
opengl renderers. However, sometimes devicetrees may not specify the
rotation or incorrectly specify it. So, also introduce a command line
argument to quickly test different rotations. This also helps in
quickly identifying the rotation at which the camera is mounted in
the device if kernel developer already doesn't know it.
