Revert "dt-bindings: clock: mobileye,eyeq5-clk: add bindings"

Switch from one sub-node per functionality in the system-controller to a
single node representing the entire OLB instance. This is the
recommended approach for controllers handling many different
functionalities; it is a single controller and should be represented by
a single devicetree node.

The clock bindings is removed and all properties will be described by:
soc/mobileye/mobileye,eyeq5-olb.yaml
