[Intel-gfx] [PATCH 03/10] drm/i915: Extract framebufer CCS offset checks into a function

From: Dhinakaran Pandiyan <dhinakaran.pandiyan at intel.com>
intel_fill_fb_info() has grown quite large and wrapping the offset checks
into a separate function makes the loop a bit easier to follow.
v2: Skip the check for non-CCS planes. (Mika)
