This series adds support for tracking Arm SCMI statistics [Patch 2/3]
A config option to enable this [Patch 2]
Cleans up a unneeded call to handle_scmi_info [Patch 1]
In [Patch 4] a selection of new debugfs entries to present these statistics
Then finally in [Patch 5] enabled writing on the debugfs entries to reset stats

Based on v6.9, Tested on Arm Juno [1]

Thanks,
Luke
