commit 65a72f51708b382cf5e67af5909c473cbe6262f2

    tcl/target/stm32f4: fix: reduce adapter speed before reset
    
    The reset-init hook for this target speeds up the CPU clock and JTAG adapter
    speed. When the target is reset running with high adapter speed, a series of
    warnings "DAP transaction stalled (WAIT) - slowing down" will be generated
    since the adapter speed is not reduced to fit the slower CPU speed.
    Fix: reduction of the adapter speed before a reset is performed.
