[PATCH v9 7/9] ARM: dts: sun8i: a83t: Add MIPI CSI-2 controller node

[Paul Kocialkowski <paulk@sys-base.io>]

From: Paul Kocialkowski <paul.kocialkowski@bootlin.com>

MIPI CSI-2 is supported on the A83T with a dedicated controller that
covers both the protocol and D-PHY. It is connected to the only CSI
receiver with a fwnode graph link. Note that the CSI receiver supports
both this MIPI CSI-2 source and a parallel source.

An empty port with a label for the MIPI CSI-2 sensor input is also
defined for convenience.
