When introduced, IRQFD resampling worked on POWER8 with XICS. However
KVM on POWER9 has never implemented it - the compatibility mode code

native
XIVE mode does not handle INTx in KVM at all.
This moved the capability support advertising to platforms and stops
advertising it on XIVE, i.e. POWER9 and later.

Or I could move this one together with KVM_CAP_IRQFD. Thoughts?
Ping?

I don't mind moving this around, but I object to the #ifdefery.
This option is always selected on arm64, so it can safely be added
to the list without any condition.
Thanks,
