net: enetc: add basic operations to the FDB table

The FDB table is used for MAC learning lookups and MAC forwarding lookups.
Each table entry includes information such as a FID and MAC address that
may be unicast or multicast and a forwarding destination field containing
a port bitmap identifying the associated port(s) with the MAC address.
FDB table entries can be static or dynamic. Static entries are added from
software whereby dynamic entries are added either by software or by the
hardware as MAC addresses are learned in the datapath.

The FDB table can only be managed by the command BD ring using table
management protocol version 2.0. Table management command operations Add,
Delete, Update and Query are supported. And the FDB table supports three
access methods: Entry ID, Exact Match Key Element and Search. This patch
adds the following basic supports to the FDB table.

ntmp_fdbt_update_entry() - update the configuration element data of a
specified FDB entry

ntmp_fdbt_delete_entry() - delete a specified FDB entry

ntmp_fdbt_add_entry() - add an entry into the FDB table

ntmp_fdbt_search_port_entry() - Search the FDB entry on the specified
port based on RESUME_ENTRY_ID.
