    common/cnxk: support to enable disable SQ

    Added a new ROC API to disable SQB aura FC and update SQ state
    to disabled state in TX queue stop.

    The same SQ status is verified during sq flush to enable or
    disable SQB aura FC during ethdev teardown.

    This fix reduces teardown time by 90%.

    common/cnxk: optimize ethdev teardown time

    API mbox_alloc_msg_npa_aq_enq() mbox is called if SQ needs
    to be updated from mbox response else mbox call to kernel
    is bypassed reducing the time taken to complete
    roc_nix_tm_sq_aura_fc() function.

    This reduces ethdev teardown time by 20%.
