[media] media: i2c: m5mols: m5mols_core: constify v4l2_subdev_pad_ops structures

v4l2_subdev_pad_ops structures are stored in the pad field
of the v4l2_subdev_ops structure and this field is of type const.
As the v4l2_subdev_pad_ops structures are never modified, they can be
declared as const.
Done using Coccinelle:
