For the mainboard with AMD Family 10, if we make clean and make again,

it will fail. why?

After make clean, .c files created by iasl are still left in the build
folder, it will match the rule of
	$(obj)/%.o: $(obj)/%.c $(obj)/config.h
		@printf "    CC         $(subst $(obj)/,,$(@))\n"
		$(CC) -MMD $(CFLAGS) -c -o $@ $<
it will miss the rule which should be applied.
	define objs_asl_template
	       ....

So we move the .c file back to .hex (or other suffix? or delete?).
This patch will work after make distclean, otherwise nobody will rename
the .c.
