pc-bios/s390-ccw: Generate and include dependency files in the Makefile
The Makefile of the s390-ccw bios does not handle dependencies of the
*.c files from the headers yet, so that you often have to run a "make
clean" to get the build right when one of the headers has been changed.
Let's make sure that we generate and include dependency files for all
*.c files now to avoid this problem in the future.
