Subject: [PATCH V2 1/3] dt-bindings: interconnect: qcom,msm8998-bwmon: Add X1E80100 BWMON instances

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.

Signed-off-by: Sibi Sankar <quic_sibis@...cinc.com>
---

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