Document X1E80100 BWMONs, which has multiple (one per cluster) BWMONv4
instances for the CPU->LLCC path and one BWMONv5 instance for LLCC->DDR
path. Also make the opp-table optional for the X1E cpu-bwmon instances,
since they use the same opp-table between them.

v2:
* Allow for opp-tables to be optional on X1E cpu-bwmon instances. [Konrad]
* Drop Rb from Krzysztof due to more bindings changes.

I think we can just drop the opp-table child node from required altogether,
bindings shouldn't care about where the OPP table (which is referenced in
the operating-points-v2 property) comes from

Thanks, will break ^^ into a separate patch for the
next re-spin.
