firewire: mark some structs const
Instances of struct file_operations and struct fw_card_driver can be
qualified as "const". Ditto with struct fw_descriptor.data, struct
fw_device_id, and predefined instances of struct fw_address_region,
at least in the current implementation.
Data qualified as const is placed into the .rodata section which won't
be mixed with dirty data.
