    layerscape: switch to Linux 6.12
    
    Linux 6.12 has been validated on Layerscape platforms, including NXP
    reference boards and multiple custom designs. Tests covered system
    boot, networking, storage, and common peripherals, with no regressions
    observed.
    
    Enable 6.12 as the default to continue broader testing and integration.
