I think the prefix can be just rte_bus_ instead of rte_eal_bus_.

Why the bus list is public?

I am not convinced we should link a generic bus to drivers and devices.
What do you think of having rte_pci_bus being a rte_bus and linking
with rte_pci_device and rte_pci_driver lists?
I'm thinking to something like that:
struct rte_bus {
TAILQ_ENTRY(rte_bus) next;
const char *name;
rte_bus_scan_t scan;
rte_bus_match_t match;
};
struct rte_pci_bus {
struct rte_bus bus;
struct rte_pci_driver_list pci_drivers;
struct rte_pci_device_list pci_devices;
};

By removing the lists from rte_bus as suggested above, do you still need
a priority for this constructor?

Do we need to know the bus associated to a driver in rte_driver?
Bus and driver are already associated in rte_device.
