kvm tools: mark our PCI card as PIO and MMIO able
A recent -next patch named "PCI: Ignore BAR contents when
firmware left decoding disabled" has pointed out that PCI
cards are supposed to declare that they have either PIO or
MMIO BARs by disabling them if it didn't.
Fix it by correctly marking our emulated PCI card as PIO/MMIO
enabled.
