Use the full compatible string: analogix,anx7814.yaml

Don't forget to update this too.

Can drop the description as there's nothing specific to this device.

I don't' think you need to specify this. You can drop it (better double check
with Rob, though)

This should be "bridge at 38 {", since node names are supposed to
match the class of the device instead of the name of the device. I guess.
