Wire phylink_ethtool_nway_reset() as the .nway_reset ethtool operation, allowing userspace to restart PHY autonegotiation via 'ethtool -r'.

A warm reset on boards using an EEPROM-only strap configuration (where no MAC address is set in the image) can cause the driver to incorrectly revert to RGMII mode. This occurs because the ENET_CONFIG_LOAD_STARTED bit may not persist or behave as expected. Update pci11x1x_strap_get_status() to use revision-specific validation: - For PCI11x1x A0: Continue using the legacy check (config load started or reset protection) to validate the SGMII strap. - For PCI11x1x B0 and later: Use the newly available STRAP_READ_USE_SGMII_EN_ bit in the upper strap register to validate the lower SGMII_EN bit. This ensures the SGMII interface is correctly identified even after a warm reboot.

The variable chip_rev stores the value read from the FPGA_REV register and represents the FPGA revision. Rename it to fpga_rev to better reflect its meaning. No functional change intended.

These three upstream patches provide fixes to the Microchip lan743x driver,
plus add capability for using "ethtool -r" to restart autonegotiation on
the interface.
469faa5 net: lan743x: rename chip_rev to fpga_rev
e783e40 net: lan743x: fix SGMII detection on PCI1xxxx B0+ during warm reset
8636385 net: microchip: lan743x: add ethtool nway_reset support
These patches picked clean and were tested on BlueField-4 hardware,
which uses the board-level Microchip LAN743x device.
