[Intel-gfx] [PATCH i-g-t v2 3/9] tests/kms_plane_scaling: Fix basic scaling test, v2.

[Maarten Lankhorst]

From: Mahesh Kumar <mahesh1.kumar at intel.com>

PIPEC doesnt have 3rd plane in GEN9. So, we skip the
3rd plane related scaling test where 2nd OVERLAY
plane is not available.

Restricting downscaling to (9/10)x original size of the
image to avoid "Max pixel rate limitation" of the hardware.

Later patches in this series will cover corner cases of
scaling.

Changes since v1:
- Move out the code reshuffle to a separate commit. (Maarten)
  This makes it more clear what's fixed.
