In my previous commit v10.10.0-48-g2d222ecf6e I've made us enable
I/O APIC when there is an IOMMU with EIM. This works well. What
does not work is case when there's just an IOMMU without EIM but
with 256+ vCPUS. Problem is that post parsing happens in two
stages: general domain post parse (where
qemuDomainDefEnableDefaultFeatures() is called) and then per
device post parse (where qemuDomainIOMMUDefPostParse() is
called). Now, in aforementioned case it is the device post parse
phase where EIM is enabled but the code that would enable
VIR_DOMAIN_FEATURE_IOAPIC has already run.
To resolve this, make the domain post parse callback "foresee"
the future enabling of EIM so that it can turn on I/O APIC
beforehand.
