This commit is based on 20231024130048.14749-1-shawn.sung@mediatek.com.

This bug is found when running IGT tests.
For CRTCs that doesn't support rotation should still return
DRM_MODE_ROTATE_0, otherwise the test will fail to restart.
Returns the hardware capabilities accordingly.

Changes in v3:
- Return 0 (not support) if rotation capabilities is not defined
  in the driver data.

Changes in v2:
- Restore DRM_MODE_ROTATE_180 (reflect x + reflect y = rotate 180)
- Define supported rotations in the driver data
