[PATCH v5 3/4] staging/intel-ipu3: Make use of V4L2_CAP_IO_MC

[Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx>]

Set the V4L2_CAP_IO_MC capability flag and remove the driver specific
vidioc_enum_{input,output}, vidioc_g_{input,output} and
vidioc_s_{input,output} callbacks.

* Changes since v4
- Set V4L2_CAP_IO_MC for all nodes unconditionally. The framework will
  disallow them for V4L2_CAP_META_* nodes.
