[PATCH 02/14] iio: adc: rzg2l_adc: Use devres helpers to request pre-deasserted reset controls

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Starting with commit d872bed85036 ("reset: Add devres helpers to request
pre-deasserted reset controls"), devres helpers are available to simplify
the process of requesting pre-deasserted reset controls. Update the
rzg2l_adc driver to utilize these helpers, reducing complexity in this
way.
