[Nouveau] [PATCH 01/40] drm/nouveau/nvkm/subdev/bios/init: Demote obvious abuse of kernel-doc

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:584: warning: Function
parameter or member 'init' not described in 'init_reserved'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:611: warning: Function
parameter or member 'init' not described in 'init_done'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:622: warning: Function
parameter or member 'init' not described in
'init_io_restrict_prog'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:659: warning: Function
parameter or member 'init' not described in 'init_repeat'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:685: warning: Function
parameter or member 'init' not described in
'init_io_restrict_pll'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:725: warning: Function
parameter or member 'init' not described in 'init_end_repeat'

NB: Trimmed for brevity (lots of these!)
