hpet: Make number of timers configurable
One HPET block supports up to 32 timers. Allow to instantiate more than the recommended and implemented minimum of 3. The number is configured via the qdev property "timers". It is also saved/restored so that it need not match between migration peers. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
