This changes the *_run_on_cpu APIs (and helpers) to pass data in a
run_on_cpu_data type instead of a plain void *. This is because we
sometimes want to pass a target address (target_ulong) and this fails on
32 bit hosts emulating 64 bit guests.

CPUState is a fairly common pointer to pass to these helpers. This means
if you need other arguments for the async_run_on_cpu case you end up
having to do a g_malloc to stuff additional data into the routine. For
the current users this isn't a massive deal but for MTTCG this gets
cumbersome when the only other parameter is often an address.
This adds the typedef run_on_cpu_func for helper functions which has an
explicit CPUState * passed as the first parameter. All the users of
run_on_cpu and async_run_on_cpu have had their helpers updated to use
CPUState where available.

[Sergey Fedorov:
- eliminate more CPUState in user data;
- remove unnecessary user data passing;
- fix target-s390x/kvm.c and target-s390x/misc_helper.c]

Eliminate redundant and incorrect booke206_page_size_to_tlb function
from ppce500_spin.c in preference to previously existing but newly
exported definition from e500.c
Defect analysis:
The booke206_page_size_to_tlb function in e500.c was updated in commit
2bd9543 "ppc: booke206: use MAV=2.0 TSIZE definition, fix 4G pages" to
reflect a change in the definition of MAS1_TSIZE_SHIFT from 8
(corresponding to a min TLB page size of 4kb) to a value of 7 (TLB
page size 2k). The booke206_page_size_to_tlb() function defined in
ppce500_spin.c was never updated to reflect the change in
MAS1_TSIZE_SHIFT.
In http://lists.nongnu.org/archive/html/qemu-ppc/2016-06/msg00533.html,
Scott Wood suggested this "root cause" explanation:
SW> The patch that changed MAS1_TSIZE_SHIFT from 8 to 7 was around the
SW> same time as the patch that added this code, which is probably why
SW> adjusting it got missed. Commit 2bd9543cd3 did update the
SW> equivalent code in ppce500_mpc8544ds.c, which now resides in
SW> hw/ppc/e500.c and has been changed to not assume a power-of-2
SW> size. The ppce500_spin version should be eliminated.

The spinning struct is in guest endianness, so we need to initialize
its variables in guest endianness too.
