octeonxt2-af: mcs: Fix per port bypass config

For each lmac port, MCS has two MCS_TOP_SLAVE_CHANNEL_CONFIGX
registers. For CN10KB both register need to be configured for the
port level mcs bypass to work. This patch also sets bitmap
of flowid/secy entry reserved for default bypass so that these
entries can be shown in debugfs.
