[00/30] media: atomisp: Register only 1 /dev/video# node + cleanups

Hi All,

Here is an atomisp patch-series to continue the simplification /
exotic feature removal of atomisp. Specifically this series
makes atomisp register only 1 /dev/video# node.

The other patches are some preparation + follow-up work for
this change, as well as a whole bunch of folow-up clean-ups.

The cleanups focus on removing the various count / users functions
which atomisp used before when there were multiple nodes. This
is preparation work for eventually allowing opening the same
node multipe-times, as is normal for standard v4l2 /dev/video#
nodes.

Regards,

Hans
