    drm/amd/display: make flip_timestamp_in_us a 64-bit variable
    
    [ Upstream commit 6fb12518ca58412dc51054e2a7400afb41328d85 ]
    
    [Why]
    This variable currently overflows after about 71 minutes. This doesn't
    cause any known functional issues but it does make debugging more
    difficult.
    
    [How]
    Make it a 64-bit variable.
