    drm/i915/display: Expose AuxCCS frame buffer modifiers for Xe
    
    Now that we have fixed the DPT handling we can undo the nerf which was
    done in cf48bddd31de ("drm/i915/display: Disable AuxCCS framebuffers if
    built for Xe").
    
    Tested with KDE Wayland, on Lenovo Carbon X1 ADL-P:
    
            [PLANE:32:plane 1A]: type=PRI
                    uapi: [FB:242] AR30 little-endian (0x30335241),0x100000000000008,2880x1800, visible=visible, src=2880.000000x1800.000000+0.000000+0.000000, dst=2880x1800+0+0, rotation=0 (0x00000001)
                    hw: [FB:242] AR30 little-endian (0x30335241),0x100000000000008,2880x1800, visible=yes, src=2880.000000x1800.000000+0.000000+0.000000, dst=2880x1800+0+0, rotation=0 (0x00000001)
    
    Display working fine - no artefacts, no DMAR/PIPE faults.
    
    v2:
     * Adjust patch title. (Rodrigo)
