[PATCH 3/4] drivers: media: i2c: imx471: Add Device Tree matching support

[Danila Tikhonov <danila@mainlining.org>]

The IMX471 driver currently only supports probing via ACPI. Add OF
device ID table with "sony,imx471" compatible string and <linux/of.h>
header to allow probing on Device Tree based platforms.
