    amd/hudson/pi: Fix position of hudson_fwm
    
    AMDFWTOOL calculates the location of the amdfw based on the
    CONFIG_ROM_SIZE. If HUDSON_FWM_POSITION does not match that location the
    resulting rom does not boot.
    
    This patch forces the position of HUDSON_FWM_POSITION to be the
    position calculated by amdfwrom.
    
    Tested on a Bettong board with a 16MiB flash.
