[PATCH 3/4] ALSA: firewire: fix all kernel-doc warnings

[Randy Dunlap <rdunlap@infradead.org>]

Add missing comment for struct member @messages.
Use the struct keyword for a struct's kernel-doc heading.
Add missing comments for nested aggregate structs.
Repair some typos.

Warning: include/uapi/sound/firewire.h:97 struct member 'messages' not described in 'snd_firewire_event_ff400_message'
Warning: ../include/uapi/sound/firewire.h:220 cannot understand function prototype: 'struct snd_firewire_motu_register_dsp_parameter'
