display: Add support orientation control on ext display

- The required orientation on External can be set using the
  properyt sys.ext_orientation.
- Values can be HAL_TRANSFORM_ROT_90, HAL_TRANSFORM_ROT_270
- According to the value set, the FB_TARGET for External will
  be rotated and positioned as per aspect ratio on Ext
- For YUV(video layer) it just calculates the position, as the
  rotation should be the source orientation
- This feature is supported only for low resolution panel.
