media: v4l2-subdev: Rename .init_cfg() operation to .init_state()

The subdev .init_cfg() operation is affected by two issues:

- It has long been extended to initialize a whole v4l2_subdev_state
instead of just a v4l2_subdev_pad_config, but its name has stuck
around.

- Despite operating on a whole subdev state and not being directly
exposed to the subdev users (either in-kernel or through the userspace
API), .init_cfg() is categorized as a subdev pad operation.

This participates in making the subdev API confusing for new developers.
Fix it by renaming the operation to .init_state(), and make it a subdev
internal operation.
