[PATCH 1/2] mfd: cros_ec: Remove parent field

[Javier Martinez Canillas <javier.martinez@collabora.co.uk>]

From: Gwendal Grignou <gwendal@chromium.org>

parent and dev were pointing to the same device structure.
parent is unused, removed.

Changes since v2: None

Changes since v1:
 - Added Heiko Stuebner and Gwendal Grignou Tested-by tag
 - Added Lee Jones Acked-by tag
 - Use cros_ec instead of cros ec in the subject line to be consistent.
