Replace the V4L2_IDENT_* usage with tveeprom-specific defines. This header
is deprecated, so those defines shouldn't be used anymore.
The em28xx driver is the only one that uses the tveeprom audio_processor
field, so that has been updated to use the new tveeprom AUDPROC define.

as well.
This means that bridge drivers no longer have to check for the match.type

This patch corrects the link_notify handler to support more complex
pipelines, including fimc-lite and fimc-is entities.
After the FIMC-IS driver addition the assumptions made in the link_notify
callback are no longer valid, e.g. the link between fimc-lite subdev and
its video node is not immutable any more and there is more subdevs than
just sensor, MIPI-CSIS and FIMC(-LITE).
The graph is now walked and for each video node found a media pipeline
which ends at this node is disabled/enabled (the subdevs are powered
on/off).

Currently the media device link_notify callback is invoked before the
actual change of state of a link when the link is being enabled, and
after the actual change of state when the link is being disabled.
This doesn't allow a media device driver to perform any operations
on a full graph before a link is disabled, as well as performing
any tasks on a modified graph right after a link's state is changed.
This patch modifies signature of the link_notify callback. This
callback is now called always before and after a link's state change.
To distinguish the notifications a 'notification' argument is added
to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates
notification before link's state change and
MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after
link flags change.
