media: vsp1: Refactor display list configure operations

The entities provide a single .configure operation which configures the
object into the target display list, based on the vsp1_entity_params
selection.

Split the configure function into three parts, '.configure_stream()',
'.configure_frame()', and '.configure_partition()' to facilitate
splitting the configuration of each parameter class into separate
display list bodies.
