target/s390x: introduce internal.h

cpu.h should only contain what really has to be accessed outside of
target/s390x/. Add internal.h which can only be used inside target/s390x/.

Move everything that isn't fast enough to run away and restructure it
right away. We'll move all kvm_* stuff later.

Minor style fixes to avoid checkpatch warning to:
- struct Lowcore: "{" goes into same line as typedef
- struct LowCore: add spaces around "-" in array length calculations
- time2tod() and tod2time(): move "{" to separate line
- get_per_atmid(): add space between ")" and "?". Move cases by one char.
- get_per_atmid(): drop extra paremthesis around (1 << 6)

Change license of new file to GPL2+ and keep copyright notice.

target/s390x: Move exception-related functions to a new excp_helper.c file

These functions can not be compiled with --disable-tcg. But since we
need the other functions from helper.c in the non-tcg build, we can also
not simply remove helper.c from the non-tcg builds. Thus the problematic
functions have to be moved into a separate new file instead that we
can later omit in the non-tcg builds.
