    drm/xe/fbdev: Limit the usage of stolen for LNL+
    
    As per recommendation in the workarounds:
    WA_22019338487
    
    There is an issue with accessing Stolen memory pages due a
    hardware limitation. Limit the usage of stolen memory for
    fbdev for LNL+. Don't use BIOS FB from stolen on LNL+ and
    assign the same from system memory.
    
    v2: Corrected the WA Number, limited WA to LNL and
        Adopted XE_WA framework as suggested by Lucas and Matt.
    
    v3: Introduced the waxxx_display to avoid tipping on other WA.
        Used xe_root_mmio_gt and avoid the for loop.
        (Suggested by Lucas)
