ieee1394: change deprecation status of dv1394 

Nobody ported ffmpeg from dv1394 to rawiso yet, and there is no
justification to remove dv1394 right now.

Nevertheless, a strong deprecation of this ABI makes a lot of sense,
especially as Kristian H's drivers shape up to be an attractive
alternative to the existing ones.  But we don't have a schedule at the
moment.

What: dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
Contact: linux1394-devel@lists.sourceforge.net
Description:
New application development should use raw1394 + userspace libraries
instead, notably libiec61883 which is functionally equivalent.
Users:
ffmpeg/libavformat (used by a variety of media players)
dvgrab v1.x (replaced by dvgrab2 on top of raw1394 and resp. libraries)

What: dv1394 driver (CONFIG_IEEE1394_DV1394)
When: June 2007
Why: Replaced by raw1394 + userspace libraries, notably libiec61883. This
shift of application support has been indicated on www.linux1394.org
and developers' mailinglists for quite some time. Major applications
have been converted, with the exception of ffmpeg and hence xine.
Piped output of dvgrab2 is a partial equivalent to dv1394.

What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
