drm/amd/display: add more link_hwss types and method to decide which one

Browse source

[why]
as we add more link_hwss we are making a generic way to determine which type
of link_hwss we should use.
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. So instead of passing in link and link_res
we can just pass in link_policy and swtich based on link_policy->get_link_hwss_type.
