include/boot/s390.h relies on s390 specific kernel headers. However,
some tools used this header for non-s390 code (outside of boot-loaders).
To solve this the PSW and PAGE_SIZE definitions are now in separate
header files. All includes for s390.h which are not in boot-loader code
are replaced with one of psw.h or page.h.
This fixes the compilation failure on ppc64le due to conflicting types
for `__vector128`.
