#1439022 — [PATCH 15/16] gpu: ipu-ic: allow multiple handles to ic

The image converter kernel API supports conversion contexts and
job queues, so we should allow more than one handle to the IC, so
that multiple users can add jobs to the queue.

Note however that users that control the IC manually (that do not
use the image converter APIs but setup the IC task by hand via calls
to ipu_ic_task_enable(), ipu_ic_enable(), etc.) must still be careful not
to share the IC handle with other threads. At this point, the only user
that still controls the IC manually is the i.mx capture driver. In that
case the capture driver only allows one open context to get a handle
to the IC at a time, so we should be ok there.

Thank you for the update, I'll have a proper look at this next week.
