net: mscc: ocelot: only install TCAM entries into a specific lookup and PAG 

We were installing TCAM rules with the LOOKUP field as unmasked, meaning
that all entries were matching on all lookups. Now that lookups are
exposed as individual chains, let's make the LOOKUP explicit when
offloading TCAM entries.
