[PATCH v1 06/28] leds: el15203000: Introduce to_el15203000_led() helper

[Andy Shevchenko <andy.shevchenko@xxxxxxxxx>]

Introduce a helper to replace open coded container_of() calls.
At the same time move ldev member to be first in the struct el15203000_led,
that makes container_of() effectivelly a no-op.
