S390: ccw firmware: Add bootmap interpreter

On s390, there is an architected boot map format that we can read to
boot a certain entry off the disk. Implement a simple reader for this
that always boots the first (default) entry.

S390: ccw firmware: Add Makefile

This patch adds a makefile, so we can build our ccw firmware. Also
add the resulting binaries to .gitignore, so that nobody is annoyed
they might be in the tree.

s390-ccw.img: Detect devices with stsch.

stsch is the canonical way to detect devices. As a bonus, we can
abort the loop if we get cc 3, and we need to check only the valid
devices (dnv set).

S390: ccw firmware: Add compiled blob

Now that we have all the source code ready, add a compiled blob into
the QEMU source tree, so that people without access to an s390 compiler
can run the s390-ccw firmware.
