drm/i915: Store the final plane stride in plane_state
Let's store the final plane stride in the plane state. This avoids having to pick between the normal vs. rotated stride during hardware programming. And once we get GTT remapping the plane stride will no longer match the fb stride so we'll need a place to store it anyway. v2: Keep checking fb->pitches[0] for cursor as later on we won't populate plane_state->color_plane[0].stride for invisible planes and we have been checking the cursor fb stride even for invisible planes v3: s/betwen/between in commit msg (José) v4: Check color_plane[0].stride instead of fb->pitches[0] in the skl_check_main_surface() X-tiling kludge Reviewed-by: NJosé Roberto de Souza <jose.souza@intel.com> Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180911150139.23922-1-ville.syrjala@linux.intel.com
