Subject: [PATCH 1/2] media: i2c: adv748x: Simplify regmap configuration

From: Kieran Bingham <kieran.bingham+renesas@...asonboard.com>

The ADV748x has identical map configurations for each register map. The
duplication of each map can be simplified using a helper macro such that
each map is represented on a single line.

Define ADV748X_REGMAP_CONF for this purpose and un-define after it's
use.
