This is the follow-up patch series of
https://lkml.iu.edu/hypermail/linux/kernel/2310.2/02078.html

Divide the PHYLINK adaptation and SFP modifications into two separate patch
series.

The current patch series focuses on transitioning the LAN743x driver's PHY
support from phylib to phylink.

Tested on chip PCI11010 Rev-B with Bridgeport Evaluation board Rev-1

Change List:
============
V2 -> V3:
  - Remove the unwanted parens in each of these if() sub-blocks 
  - Replace "to_net_dev(config->dev)" with "netdev".
  - Add GMII_ID/RGMII_TXID/RGMII_RXID in supported_interfaces
  - Fix the lan743x_phy_handle_exists( ) return type

V1 -> V2:
  - Fix the Russell King's comments i.e. remove the speed, duplex update in 
    lan743x_phylink_mac_config( )
  - pre-March 2020 legacy support has been removed

V0 -> V1:
  - Integrate with Synopsys DesignWare XPCS drivers
  - Based on external review comments,
  - Changes made to SGMII interface support only 1G/100M/10M bps speed
  - Changes made to 2500Base-X interface support only 2.5Gbps speed
  - Add check for not is_sgmii_en with is_sfp_support_en support
  - Change the "pci11x1x_strap_get_status" function return type from void to
    int
  - Add ethtool phylink wol, eee, pause get/set functions
