s390x: lib: sie: don't reenter SIE on pgm int

At the moment, when a PGM int occurs while in SIE, we will just reenter
SIE after the interrupt handler was called.

This is because sie() has a loop which checks icptcode and re-enters SIE
if it is zero.

However, this behaviour is quite undesirable for SIE tests, since it
doesn't give the host the chance to assert on the PGM int. Instead, we
will just re-enter SIE, on nullifing conditions even causing the
exception again.

In sie(), check whether a pgm int code is set in lowcore. If it has,
exit the loop so the test can react to the interrupt. Add a new function
read_pgm_int_code() to obtain the interrupt code.

Note that this introduces a slight oddity with sie and pgm int in
certain cases: If a PGM int occurs between a expect_pgm_int() and sie(),
we will now never enter SIE until the pgm_int_code is cleared by e.g.
clear_pgm_int().

Also add missing include of facility.h to mem.h.

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.
