Subject: [PATCH net-next 12/12] net: mscc: ocelot: unexpose ocelot_vcap_policer_{add,del}

From: Vladimir Oltean <vladimir.oltean@....com>

Remove the function prototypes from ocelot_police.h and make these
functions static. We need to move them above their callers. Note that
moving the implementations to ocelot_police.c is not trivially possible
due to dependency on is2_entry_set() which is static to ocelot_vcap.c.
