KVM: X86: Lower the default timer frequency limit to 200us
Anthoine reported:
The period used by Windows change over time but it can be 1
milliseconds or less. I saw the limit_periodic_timer_frequency
print so 500 microseconds is sometimes reached.
As suggested by Paolo, lower the default timer frequency limit to a
smaller interval of 200 us (5000 Hz) to leave some headroom. This
is required due to Windows 10 changing the scheduler tick limit
from 1024 Hz to 2048 Hz.
