media: renesas: vsp1: Get configuration from partition instead of state

Entities access various piece of information from the subdev state when
configuring a partition. The same data is available through the
partition structure passed to the .configure_partition() operation. Use
it to avoid accessing the state, which will simplify moving to the V4L2
subdev active state API.
