iwlwifi: separate nic_config for different NIC
Different NIC has different requirements for configuration. Currently all 5000 series hardware and later share the same configuration function even though they do not need the same configurations. Fix this by separating the needed configuration actions for each hardware model. .5000 series: L1-ASPM H/W bug work-around configure radio write CSR_HW_IF_CONFIG_REG for uCode use work-around for NIC get stuck after early PCIe power off .1000 series: write CSR_HW_IF_CONFIG_REG for uCode use setting digital SVR for 1000 card to 1.32V .6000 series: configure radio write CSR_HW_IF_CONFIG_REG for uCode use write CSR_GP_DRIVER_REG to indicate radio sku Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
