Laurent Pinchart cebd8c532f v4l: vsp1: Add pipe index argument to the VSP-DU API
In the H3 ES2.0 SoC the VSP2-DL instance has two connections to DU
channels that need to be configured independently. Extend the VSP-DU API
with a pipeline index to identify which pipeline the caller wants to
operate on.
