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.

Document the compatibles used to describe the Bandwidth Monitors
present on the SM8550 platform.
A BWMON v4 IP monitors the CPU bandwidth, and a v5 does the LLCC
bandwidth monitoring.
This is described by adding "llcc" and "cpu" into the compatible
strings to differentiate the BWMON IPs.

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.
