[PATCH 04/12] media: ipu3-cio2: Store dev pointer in struct cio2_bridge

[Hans de Goede <hdegoede@redhat.com>]

Store the dev pointer in struct cio2_bridge instead of passing it
around 3 levels deep.

This takes up slightly more memory but further patches in this series
add more data which needs to be passed around making passing
everything as arguments cumbersome and those further patches also
add data to struct cio2_bridge.

To be consistent with these upcoming patches also add
the dev pointer to struct cio2_bridge.
