Series media: renesas: vsp1: Add support for IIF | expand

Commit Message

Enable the "FrameEnd" interrupt to support the VSPX operations.

The frame completion interrupt signals that the transfer of
the config buffer and image buffer to the ISP has completed.

Enable the interrupt source if the pipe has an IIF entity, such as
in the VSPX case.
