media: atomisp: Remove support for custom run-mode v4l2-ctrl on sensors

Remove the support to update a V4L2_CID_RUN_MODE run-mode control
on sensors when changing the atomisp run-mode or directly by calling
the custom ATOMISP_IOC_S_SENSOR_RUNMODE IOCTL.

No sensor drivers implement this and having custom controls / IOCTLs
is undesirable.

Even if there was such a control on sensors then userspace should directly
talk to the sensor v4l2-subdev, rather than relying on a custom IOCTLs
on the output /dev/video# node to pass this through to the senor.
