In order to support a userspace IOAPIC interacting with an in kernel
APIC, the EOI exit bitmaps need to be configurable.
If the IOAPIC is in userspace (i.e. the irqchip has been split), the
EOI exit bitmaps will be set whenever the GSI Routes are configured.
In particular, for the low 24 MSI
The periodic kvmclock sync can be an undesired source of latencies.
When running cyclictest on a guest, a latency spike is visible.
With kvmclock periodic sync disabled, the spike is gone.
Guests should use ntp which means the propagations of ntp corrections
from the host clock are unnecessary.
