[PATCH v10 02/22] dt-bindings: media: i2c: max96717: add support for I2C ATR

[Dumitru Ceclan via B4 Relay <devnull+dumitru.ceclan.analog.com@kernel.org>]

From: Cosmin Tanislav <demonsingur@gmail.com>

MAX96717 is capable of address translation for the connected I2C slaves.

Add support for I2C ATR while keeping I2C gate for compatibility to
support this usecase.
