cpu: init vmstate for ticks and clock offset

Ticks and clock offset used by CPU timers have to be saved in vmstate.
But vmstate for these fields registered only in icount mode.
Missing registration leads to breaking the continuity when vmstate is loaded.
This patch introduces new initialization function which fixes this.
