Subject: [PATCH 01/13] dt-bindings: soc: mobileye: set `#clock-cells = <1>`
for all compatibles
Some compatibles expose a single clock. For those, we used to let them
using `#clock-cells = <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.
Side benefit: dt-bindings is simpler.
