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
