dt-bindings: staging: media: i2c: Add bindings for Maxim Integrated MAX96712
Commit Message
Add bindings for Maxim Integrated MAX96712 deserializer. The MAX96712
deserializer converts GMSL2 or GMSL1 serial inputs into MIPI CSI-2 D-PHY
or C-PHY formatted outputs.

Drop 'staging'. We don't do staging bindings unless they are in
drivers/staging/ and then I ignore them. Though a couple snuck in.

+ MAX96712 can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1
