Public Methods
void AddRef ()Bridge or DeviceImpl will need to implement refcounting
zx::result<uint32_t> QueryIrqMode (fuchsia_hardware_pci::InterruptMode mode)These methods handle IRQ configuration and are generally called by the
PciProtocol methods, though they may be used to disable IRQs on
initialization as well.

them.

Protected Methods
void Device (zx_device_t *parent,std::unique_ptr<Config> &&config,UpstreamNode *upstream,BusDeviceInterface *bdi,boolis_bridge,boolhas_acpi,boolhas_devicetree)
Devices need to exist in both the top level bus driver class, as well
as in a list for roots/bridges to track their downstream children. These
traits facilitate that for us.
