    qoriq: switch to kernel 5.15
    
    The testing kernel has been running fine for months on a rather complex
    network setup, with one exception being a crash in
    __xfrm_state_delete(). This crash has been fixed in kernel 5.15.82, so
    let's switch the qoriq target to kernel 5.15 by default.
