amd/hudson/agesa: 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 derivative with a 16MiB flash.
