media: atomisp: ov2680: Add init_cfg pad-op

Browse source

Having an init_cfg to initialize the passed in subdev-state is
important to make which == V4L2_SUBDEV_FORMAT_TRY ops work when
userspace is talking to a /dev/v4l2-subdev# node.

Copy the ov2680_init_cfg() from the standard drivers/media/i2c/ov2680.c
driver.

This is esp. relevant once support for cropping is added where
the v4l2_subdev_state.pads[pad].try_crop rectangle needs to be set
correctly for set_fmt which == V4L2_SUBDEV_FORMAT_TRY calls to work.
