From: Jyoti Yadav <jyoti.r.yadav@intel.com>

This patch adds subtest for testing scaling in combination with rotation
and pixel formats.

Changes since v1:
- Rework test to work with the other changes to kms_plane_scaling. (Maarten)
- Remove hardcodes for MIN/MAX_SRC_WIDTH, and use the value directly. (Maarten)
