dt-bindings: interconnect: qcom,msm8998-bwmon: Resolve MSM8998 support

Browse source

BWMONv4 has two sets of registers: one for handling the monitor itself
and one called "global" which hosts some sort of a headswitch and an
interrupt control register. We did not handle that one before, as on
SoCs starting with SDM845 they have been merged into a single contiguous
range.

To make the qcom,msm8998-bwmon less confusing and in preparation for
actual MSM8998 support, describe the global register space and introduce
new "qcom,sdm845-cpu-bwmon" compatible while keeping the
"qcom,sdm845-bwmon" as a fallback for SoCs with this merged register space
scheme.
