Subject: [PATCH v3 10/19] dt-bindings: media: i2c: max96712: deprecate enable-gpios

The MAX96712 actually has a GPIO named PWDNB, which will put the chip
in reset state when held low. Esentially, it works as an enable GPIO,
but the naming is different.

Deprecate the enable-gpios property, and add powerdown-gpios as the
rest of the GMSL chips.

Change the example to use powerdown-gpios.
