    drm/xe/display: Add support for AuxCCS
    
    Add support for mapping the auxiliary CCS buffer into the DPT page tables.
    
    This will allow for more power efficiency by enabling the render
    compression frame buffer modifiers such as
    I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS in a following patch.
    
    We do this by refactoring the code a bit so handling for the linear
    auxiliary frame buffer can be added in a tidy way. Also replace some
    hardcoded constants and tighten the loops a bit.
