amdfwtool: Use Makefile.mk for Makefile settings

When updating the Makefiles, to keep from having to update two files at
the same time, import Makefile.mk into the external Makefile. This
allows the bulk of the settings to be in a single location.

While I'm here, I adjusted the print statements to match the rest of
coreboot.
