Hariprasad Kelam ce7a6c3106 octeontx2-af: cn10k: Add RPM Rx/Tx stats support
RPM supports below list of counters as an extension to existing counters
 *  class based flow control pause frames
 *  vlan/jabber/fragmented packets
 *  fcs/alignment/oversized error packets

This patch adds support to display supported RPM counters via debugfs
and define new mbox rpm_stats to read all support counters.
