[PATCH] pci: Rename pcibios_add_device to match

Oliver O'Halloran
2021-09-13T15:47:27Z

The general convention for pcibios_* hooks is that they're named after
the corresponding pci_* function they provide a hook for. The exception
is pcibios_add_device() which provides a hook for pci_device_add(). This
has been irritating me for years so rename it.

Also, remove the export of the microblaze version. The only caller
must be compiled as a built-in so there's no reason for the export.
