This documents 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 this by adding "llcc" and "cpu" into the compatible
strings to differentiate the BWMON IPs.
