For those, we used to let them using `#clock-cells =3D <0>` (ie <&olb> reference rather than <&olb 0>). Switch away from that: enforce a cell for all compatibles. This is more straight forward, and avoids devicetree changes whenever a compatible goes from exposing a single clock to multiple ones. Also, dt-bindings get simpler. *This is an ABI break*. Change it while EyeQ5 platform support is at its infancy, without any user. More clocks might hide in each OLB as some registers are still unknown.
