Yeah, this should've been "apple,t8103-i2c", "apple,i2c" all along :/
Given that we have no i2c nodes in the dts yet and that this binding was
only added for -rc1 I think it's fine to just drop "apple,t8103-i2c"
here instead of marking it as deprecated and keeping it around forever
if Mark Kettenis also agrees.

Nit: the enum makes sense once we add t6000-i2c but right now

properties:
  compatible:
    items:
      - const: apple,t8103-i2c
      - const: apple,i2c

also works and look a bit less weird.

Either way,
