[RFC PATCH 09/11] drivers/bus: hide specific structures

Previous message (by thread): [RFC PATCH 08/11] drivers/bus: remove back reference to bus objects
Next message (by thread): [RFC PATCH 10/11] bus: introduce accessors
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]
Now that there is no bus specific object referenced in the driver
objects, we can hide rte_dpaa_bus, rte_fslmc_bus, rte_pci_bus,
rte_vmbus_bus specific structures into their bus code.

While at it:
- move enumerators only used in the bus code itself,
- remove unneeded list head structure type,
- reorder the definitions and macro manipulating the bus singleton object,
- remove inclusion of rte_bus.h and update code that relied on it,
