mem: Add a simple snoop counter per bus
This patch adds a simple counter for both total messages and a histogram for
the fan-out of snoop messages. The fan-out describes to how many ports snoops
had to be sent per incoming request / snoop-from-below. Without any
cleverness, this usually means to either all, or all but the requesting port.
