s390x: Introduce symbol for lowcore and use it

This gets rid of bunch of pointers pointing to the lowcore used in
various places and replaces it with a unified way of addressing the
lowcore.
The new symbol is not a pointer. While this will lead to worse code
generation (cannot use register 0 for addressing), that should not
matter too much for kvm unit tests.
Since the lowcore is located per definition at address 0, the symbol is
defined via the linker scripts.
The symbol also will be used to create pointers that the compiler cannot
warn about as being outside the bounds of an array.

s390x: lib: Move to GPL 2 and SPDX license identifiers

In the past we had some issues when developers wanted to use code
snippets or constants from the kernel in a test or in the library. To
remedy that the s390x maintainers decided to move all files to GPL 2
(if possible).

At the same time let's move to SPDX identifiers as they are much nicer
to read.
