dt-bindings: i2c: apple,i2c: Add apple,t6020-i2c compatible

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,i2c" anymore [1]. Use
"apple,t8103-i2c" as fallback compatible as it is the SoC the driver
and bindings were written for.

This block is compatible with t8103, so just add the new per-SoC
compatible using apple,t8103-i2c as base.
