From: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>
The subdev core code currently rely on the subdev open handler to
initialize the file handle's pad configuration, even though subdevs now
have a pad operation dedicated for that purpose.
As a first step towards migration to init_cfg, call the operation
operation in the subdev core open implementation. Subdevs that are
haven't been moved to init_cfg yet will just continue implementing pad
config initialization in their open handler.
