dt-bindings: interconnect: qcom,msm8998-bwmon: Correct SC7280 CPU compatible

Two different compatibles for SC7280 CPU BWMON instance were used
in DTS and bindings.  Correct the bindings to use the same one as in
DTS, because it is more specific.

Fixes: b7c84ae757c2 ("dt-bindings: interconnect: qcom,msm8998-bwmon: Add support for sc7280 BWMONs")
