[ Upstream commit 59faeaf80d0239412056c4495cc49097e9cea4da ]
This patch addresses review comments that were given for 705ed549148f ("perf vendor events arm64: Add AmpereOne metrics") but didn't make it to the original patch [1][2]
Changes include: A fix for backend_memory formula, use of standard metrics when possible, using #slots, renaming metrics to avoid spaces in the names, and cleanup.
