Later on we may think of introduce a link policy layer. it could be a thin layer that decide the type of link_hwss we use.

[why] Current we have hundreds of if/else or switch statement to check encoder type in dc_link level. The reason is because depending on the type of encoder dc_link needs to perform similar programming task but with different encoder interfaces.
