firewire: core: use helper inline functions to deserialize self ID packet
This commit replaces the existing implementation with the helper functions for self ID packet. Link: https://lore.kernel.org/r/20240605235155.116468-9-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>
