pci: add pcibios_release_device
Platforms may want to provide architecture-specific functionality when a pci device is released. Add a pcibios_release_device() call that architectures can override to do so. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
