[PATCH v2 2/5] media: i2c: lm3560: Fix v4l2 subdev registration

[Svyatoslav Ryhel <clamor95@gmail.com>]

The existing driver does not call media subdev registration, making it
invisible to the media framework. Since the LM3560 supports two
independent LEDs, register each LED as a separate media entity.
