s390x/tcg: properly implement the TOD
Right now, each CPU has its own TOD. Especially, the TOD will differ
based on creation time of a CPU - e.g. when hotplugging a CPU the times
will differ quite a lot, resulting in stall warnings in the guest.
Let's use a single TOD by implementing our new TOD device. Prepare it
for TOD-clock epoch extension.
Most importantly, whenever we set the TOD, we have to update the CKC
timer.
Introduce "tcg_s390x.h" just like "kvm_s390x.h" for tcg specific
function declarations that should not go into cpu.h.
