v4l: vsp1: Repair suspend resume operations for video pipelines

When a suspend/resume action is taken, the pipeline is reset and never
reconfigured.

To correct this, we establish a new flag pipe->configured and utilise
this to establish when we write a full configuration set to the current
display list.
