firewire: ohci: use devres for PCI-related resources
The PCI framework supports managed device resource to maintain the lifetime of PCI specific resources. This commit allows 1394 OHCI driver to utilize it. Link: https://lore.kernel.org/r/20230604054451.161076-3-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>
