Use the `tpi_info` struct definition, similar to the Linux kernel, in
the lowcore struct. This change allows us to use simple assignments
instead of using casts. Additionally, there is the advantage that the
lowcore definition from the s390-tools now looks more similar to the
lowcore definition used by the Linux kernel.

Now that we made sure that s390.h can be used with our minimal libc
implementation and glibc move s390.h to `include/boot/s390.h`. While
at it, make sure that s390.h is assembler compatible as it will be
used later in the PV boot loader and include s390.h in ipl.h as
PAGE_SIZE is used there.

Update zipl DASD standalone dumpers for single-volume, multi-volume and FBA
to drop the sets of zero pages when dumping memory to disk. Thus, all
continuous sets of zero-megabytes in the memory are dropped during the dump
stage.
