This is all that is currently needed, as all partitions span the whole image vertically. The horizontal window size is retrieved in the .configure_partition() handler from the vsp1_partition_window structure, and the vertical window size from the subdev state. Accessing the subdev state in the .configure_partition() handler is problematic in the context of moving to the V4L2 subdev active state API, as .configure_partition() is called in non-interruptable context, and the state lock can't be taken. To avoid this, start by storing the vertical size in the window, replacing the custom vsp1_partition_window structure with a v4l2_rect. Retrieving the vertical size from the window in .configure_partition() will be done in a subsequent change.
