Right now AB vote is calulated as a percentage of total possible BW which causes higher AB vote than actual GPU bus transactions in some use cases. We can calculate actual GPU bus BW if we know bus_width for the target. This change will derive AB vote based on bus_width defined in dtsi and VBIF counters. Define bus_width in number of bytes in target gpu dtsi file to use this new AB vote calculation.
