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.
