net/ice/base: use report default config to get PHY capa

In case of new link establishment flow we should use
Report Default Configuration if FW AQ API version
supports it. This patch adds check function for Report
Default Configuration support and updates ice_set_fc(),
ice_cfg_phy_fec() and ice_aq_get_phy_caps() accordingly.
