The virtio MMIO code attempts to map PCI device IDs to virtio MMIO
device IDs by subtracting 0x1000 and adding 1, however this conversion
only works for NET and BLK devices.
This patch uses the subsys_id (which is actually the virtio device ID
for virtio-mmio devices) instead of the PCI device ID when populating
the mmio device header.
