[Intel-gfx] [PATCH 11/22] drm/i915: Don't pass plane+plane_state to intel_pin_and_fence_fb_obj()

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

intel_pin_and_fence_fb_obj() only needs the framebuffer, and the desird
rotation (to find the right GTT view for it), so no need to pass all
kinds of plane stuff.
