Now that the netboot code has been merged into the main s390-ccw.img,
it also does not make sense to keep the build rules in a separate
file. Thus let's merge netboot.mak into the main Makefile.

Since the netboot code has now been merged into the main s390-ccw.img
binary, we don't need the separate s390-netboot.img anymore. Remove
it and the code that was responsible for loading it.

We originally built a separate binary for the netboot code since it
was considered as experimental and we could not be sure that the
necessary SLOF module had been checked out. Time passed, the code
proved its usefulness, and the build system nowadays makes sure that
the SLOF module is checked out if you have a s390x compiler available
for building the s390-ccw bios. So there is no real compelling reason
anymore to keep the netboot code in a separate binary. Linking the
code together with the main s390-ccw.img will make future enhancements
much easier, like supporting more than one boot device.

We are already using the libc from SLOF for the s390-netboot.img, and
this libc implementation is way more complete and accurate than the
simple implementation that we currently use for the s390-ccw.img binary.
Since we are now always assuming that the SLOF submodule is available
when building the s390-ccw bios (see commit bf6903f6944f), we can drop
the simple implementation and use the SLOF libc for the s390-ccw.img
binary, too.
Additionally replace sclp_print calls with puts/printf now that it is
available.

We are going to link the SLOF libc into the s390-ccw.img, and this
libc needs more memory for providing space for malloc() and friends.
Thus bump the memory size that we reserve for the bios to 3 MiB
instead of only 2 MiB. While we're at it, add a proper check that
there is really enough memory assigned to the machine before blindly
using it.

This reverts commit 3c5f86a22686ef475a8259c0d8ee714f61c770c9.
Changing the order here caused a regression with the "tuxrun"
kernels (from https://storage.tuxboot.com/20230331/) - ATA commands
fail with a "ata1: lost interrupt (Status 0x58)" message.
Apparently we need to wire the interrupt here first before
realizing the device, so revert the change to the original
behavior.
