Right now we configure the pagesize quite early, when initializing KVM.
This is long before system memory is actually allocated via
memory_region_allocate_system_memory(), and therefore memory backends
marked as mapped.
Instead, let's configure the maximum page size after initializing
memory in s390_memory_init(). cap_hpage_1m is still properly
configured before creating any CPUs, and therefore before configuring
the CPU model and eventually enabling CMMA.
This is not a fix but rather a preparation for the future, when initial
memory might reside on memory backends (not the case for s390x right now)
We will replace qemu_getrampagesize() soon by a function that will always
return the maximum page size (not the minimum page size, which only
works by pure luck so far, as there are no memory backends).

We are going to factor out the TOD into a separate device and use const
pointers for device class functions where possible. We are passing right
now ordinary pointers that should never be touched when setting the TOD.
Let's just pass the values directly.
Note that s390_set_clock() will be removed in a follow-on patch and
therefore its calling convention is not changed.

Let the flic device handle it internally. This will allow us to later
on store floating interrupts in the flic for the TCG case.
This now also simplifies kvm.c. All that's left is the fallback
interface for floating interrupts, which is now triggered directly via
the flic in case anything goes wrong.

We want to use the same code base for TCG, so let's cleanly factor it
out.
The sigp mutex is currently not really needed, as everything is
protected by the iothread mutex. But this could change later, so leave
it in place and initialize it properly from common code.

Provides an interface for getting and setting the guest's extended
TOD-Clock via a single ioctl to kvm. If the ioctl fails because it
is not support by kvm, then we fall back to the old style of
retrieving the clock via two ioctls.

[some cosmetic fixes]
Let's do it just like the other architectures. Introduce kvm-stub.c
for stubs and kvm_s390x.h for the declarations.
Change license to GPL2+ and keep copyright notice.
As we are dropping the sysemu/kvm.h include from cpu.h, fix up includes.
