Subject: [PATCH v3 01/17] media: entity: Pass entity to get_fwnode_pad operation

Add a missing pointer to the entity in the media_entity operation
get_fwnode_pad. There are no implementers of this op yet, but a future
entity that does so will almost certainly need a reference to itself
to carry out the work.

Fixes: ae45cd5efc120 ("[media] media: entity: Add get_fwnode_pad entity
operation")
