[why] Ideally link capability should be independent from the link configuration that we decide to use in enable link. Otherwise if link capability is changed after validation has completed, we could end up enabling a link configuration with invalid configuration. This would lead to over link bandwidth subscription or in the extreme case causes us to enable HPO link to a DIO stream. [how] Add a new struct in pipe ctx called link config. This structure will contain link configuration to enable a link. It will be populated during map pool resources after we validate link bandwidth. Remove the reference of verified link cap during enable link process and use link config in pipe ctx instead.
