Subject: [PATCH 2/4] [media] omap3isp: get entity ID using media_entity_id()

The struct media_entity does not have an .id field anymore since
now the entity ID is stored in the embedded struct media_gobj.

This caused the omap3isp driver fail to build. Fix by using the
media_entity_id() macro to obtain the entity ID.
