Reset CGX/RPM MAC HW statistics at the time of driver probe()

Also added a devlink option to do the same at runtime, this will be
helpful during debug.

Usage: Reset MAC stats
devlink dev param  set  pci/0002:03:00.0 name mac_stats_reset value true
cmode runtime

Where are the stats reported? It'd be more intuitive to add the ability
to reset stats to whatever interface is used to report them. Or one of
your reset interfaces (devlink dev reload).

We are using debugfs interface to report the stats. As you had indicated previously not to take input to debugfs, we implemented devlink interface to reset the MAC stats.
