bus/auxiliary: make driver-only headers private

The auxiliary bus interface is for drivers only.
Mark as internal and move the header in the driver headers list.

While at it, cleanup the code:
- fix indentation,
- remove unneeded reference to bus specific singleton object,
- remove unneeded list head structure type,
- reorder the definitions and macro manipulating the bus singleton object,
- remove inclusion of rte_bus.h and fix the code that relied on implicit
inclusion,

common/mlx5: get PCI device address from any bus

A function is exported to allow retrieving the PCI address
of the parent PCI device of a Sub-Function in auxiliary bus sysfs.
The function mlx5_dev_to_pci_str() is accepting both PCI and auxiliary
devices. In case of a PCI device, it is simply using the device name.

The function mlx5_dev_to_pci_addr(), which is based on sysfs path
and do not use any device object, is renamed to mlx5_get_pci_addr()
for clarity purpose.

common/mlx5: support auxiliary bus

Add auxiliary bus support for Sub-Function.

As a limitation of current driver, NUMA node of device is detected
from PCI bus of device sysfs symbol link.
It will be removed once NUMA node file will be available in sysfs.
