net/ice: support RSS hash configuration in DCF mode

Browse Source 
RSS HASH should be updated and queried by application,
Add related ops ('.rss_hash_update', '.rss_hash_conf_get') for DCF.

Because DCF doesn't support configure RSS HASH, only HASH key can be
updated within ops '.rss_hash_update'.
