[PATCH u-boot v2] ARM: dts: aspeed: Add dts for ASUS Kommando IPMI card

[Anirudh Srinivasan]

Add dts for Asus Kommando IPMI card, an ast2600 based pcie bmc card.

This version of the DTS doesn't support networking due to u-boot inserting
mac delays (when it isn't really needed) and needing to misconfigure the
phy-mode in linux due to it. See discussion here [1] for more details.

Networking can be enabled in this manner currently.

aliases {
        eth0 = &mac2;
};

&mac2 {
	status = "okay";
	phy-mode = "rgmii-id";
	phy-handle = <&ethphy2>;
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_rgmii3_default>;
};

&mdio {
       status = "okay";
       pinctrl-names = "default";
       pinctrl-0 = <&pinctrl_mdio3_default>;
       #address-cells = <1>;
       #size-cells = <0>;

       ethphy2: ethernet-phy at 2 {
               reg = <0>;
       };
};

&scu {
       mac2-clk-delay = <0 0
                         0 0
                         0 0>;
};

Once u-boot is updated to not insert these clk delays, the scu node from
above can be dropped and networking should work in rgmii-id mode as
expected

Changes in v2:
- Drop ethernet node from DT
- Add info to commit message on why this was dropped (references to
  linux kernel discussion about aspeed MAC driver fixes) and how to
  re-enable it
- Link to v1: https://lore.kernel.org/r/20260228-asus-kommando-v1-1-9a288620096d@gmail.com
