    src: Increase maximum blootblock execution count
    
    Most AMD and Intel x86 hardware requires at minimum two warm
    resets when booting from S5 (power off).  This is uncomfortably
    close to the maximum bootblock execution count, and has resulted
    in unstable normal/fallback operation on some machines.
    
    Increase the maximum bootblock execution count before fallback
    to 6.  This translates to roughly 2 - 3 failed boots before fallback
    mode will engage, with an absolute worst case of pushing the reset
    button 5 times to engage fallback mode in the absence of a dedicated
    recovery jumper.
