[Intel-gfx] [RFC v3 7/9] drm/i915: Skip rotated offset adjustment for unsupported modifiers

[Dhinakaran Pandiyan]

During framebuffer creation, we pre-compute offsets for 90/270 plane
rotation. However, only Y and Yf modifiers support 90/270 rotation. So,
skip the calculations for other modifiers.
