AMD Hudson: Move the combining firmware from Python to Makefile
Maybe sooner or later python is not a default tools to build coreboot. Most of the work is done by awk now. GNU extension of gawk is not used, isn't? cat, awk, test, mv are the external tools. If XHCI or IMC firmware is not available and not defined, this script can skip integrating them.
