dt-bindings: i2c: nomadik: add mobileye,eyeq6h-i2c bindings

After EyeQ5, it is time for Mobileye EyeQ6H to reuse the Nomadik I2C
controller. Add a specific compatible because its HW integration is
slightly different from EyeQ5.

Do NOT add an example as it looks like EyeQ5 from a DT standpoint
(without the mobileye,olb property).
