sie.h was missing in arch/s390/include/uapi/asm/Kbuild and therefore missed
the "make headers_check" target.
If added it reveals that also arch/s390/include/asm/sigp.h would become uapi.
This is something we certainly do not want. So remove that dependency as well.
The header file was merged with ceae283bb2 "KVM: s390: add sie exit
reasons tables", therefore we never had a kernel release with this commit and
can still change anything.

This patch adds a new decoder of SIE intercepted instructions.
The decoder implemented as a macro and potentially can be used in
both kernelspace and userspace.
Note that this simplified instruction decoder is only intended to be
used with the subset of instructions that may cause a SIE intercept.

This patch defines tables of reasons for exiting from SIE mode
in a new sie.h header file. Tables contain SIE intercepted codes,
intercepted instructions and program interruptions codes.
