dt-bindings: opp: accept array of frequencies

Browse Source 
Devices might need to control several clocks when scaling the frequency
and voltage.  Allow passing array of clock frequencies, similarly to the
voltages.

property to uniquely identify the OPP nodes exists. Devices like power
domains must have another (implementation dependent) property.
Entries for multiple clocks shall be provided in the same field, as
array of frequencies. The OPP binding doesn't provide any provisions
to relate the values to their clocks or the order in which the clocks
need to be configured and that is left for the implementation
specific binding.
