This series adds device-tree nodes for CPSW2G and CPSW9G instance
of the CPSW Ethernet Switch on TI's J784S4 SoC. Additionally,
two device-tree overlays are also added:
1. QSGMII mode with the CPSW9G instance via the ENET EXPANSION 1
   connector.
2. USXGMII mode with MAC Ports 1 and 2 of the CPSW9G instance via
   ENET EXPANSION 1 and 2 connectors, configured in fixed-link
   mode of operation at 5Gbps link speed.

Similar to Andrew Davis patch at:
https://lore.kernel.org/r/20231117222930.228688-5-afd@ti.com/ for J721E,
similar changes are also required for J784S4 to remove dependency on the
parent node being a syscon node.

This series combines the v1 series at:
https://lore.kernel.org/r/20230522092201.127598-1-s-vadapalli@ti.com/
and the patch for Main CPSW2G node that is present in [PATCH v6 2/5] at:
https://lore.kernel.org/r/20230721132029.123881-1-j-choudhary@ti.com/
but dropped in it's next version at:
https://lore.kernel.org/r/20231019054022.175163-1-j-choudhary@ti.com/

Changes from v1 for J784S4 CPSW9G DT Support:
1. Update serdes_ln_ctrl node in k3-j784s4-main.dtsi
   to remove dependency on the parent node being a syscon node.
2. The patch for Main CPSW2G node is combined.
3. Update description in k3-j784s4-evm-quad-port-eth-exp1.dtso
   QSGMII overlay file and add product link for QSGMII
   daughtercard.
4. Add a comment in k3-j784s4-evm-usxgmii-exp1-exp2.dtso
   USXGMII overlay file for the serdes_wiz2 node since it uses
   156.25 MHz clock for USXGMII.

Changes from v6 for J784S4 Main CPSW2G node: 
1. Rename node name in k3-j784s4-main.dtsi from
   main_cpsw2g_pins_default to main_cpsw2g_default_pins,
   main_cpsw2g_mdio_pins_default to main_cpsw2g_mdio_default_pins
   and main_phy0 to main_cpsw1_phy0 based on Tony's suggestion at:
   https://lore.kernel.org/all/20230724045032.GU5194@atomide.com/
