Since halting a vCPU and how many left running do not need
to be tied together, split the s390_count_running_cpus()
call out of s390_cpu_halt() to the single caller using it:
s390_handle_wait().

Since commit da94488546 ("target/s390x: make helper.c
sysemu-only") target/s390x/helper.c is only built for
system mode, so s390_cpu_halt() and s390_cpu_unhalt()
are never called from user mode.

Commit 70ebd9ce1c ("s390x/tcg: Fault-safe memset") passed
vaddr type to access_prepare(), and commit b6c636f2cd
("s390x/tcg: Fault-safe memmove") to do_access_get_byte(),
but declared S390Access::vaddr[1,2] as target_ulong.
Directly declare these as vaddr type, and have
s390_probe_access() use that type as argument.

The s390-ccw-virtio-3.0 machine was the last one that used the
hpage_1m_allowed switch. Since we removed this machine type, we
can now remove the switch and the related code, too. This allows
us to get rid of the get_machine_class() hack and the big fat
warning comment there.
