[][HIGH][kernel][common][eth][Update Airoha EN8811H 2.5G PHY driver to v1.2.5]

[Description]
Change Airoha EN8811H 2.5G PHY driver to v1.2.5.

Change Log:
[2024/03/08] v1.2.5
1. Added surge 5R API.
2. Add CL22 and CL45 command
* MD32 8811_24030702 updated:
1. Fix the issue of external loopback
2. Fix the issue of down-shift
3. Add surge protection to support 0R and 5R mode
4. Enhance cable diag accuracy of cable length
5. Improved IoT performance and stability

=====================================================================
If your board that GMAC2 connects with Airoha EN8811H, please change
the eth node as following.

&eth {
	...

	gmac1: mac@1 {
		compatible = "mediatek,eth-mac";
		reg = <1>;
		phy-mode = "2500base-x";

		fixed-link {
			speed = <2500>;
			full-duplex;
			pause;
		};
	};

	mdio: mdio-bus {
      		#address-cells = <1>;
      		#size-cells = <0>;

      		phy15: phy@15 {
       			compatible = "ethernet-phy-id03a2.a411";
			reg = <15>;
			phy-mode = "2500base-x";
			full-duplex;
			pause;
			airoha,polarity = <1>;
			airoha,surge = <0>;
		};

       		...
	};
};

Note:
SerDes polarity setting could be configured in dts. Please refer to the
following description.
Tx Reverse, Rx Normal:
		airoha,polarity = <0>;
Tx Normal, Rx Normal:
		airoha,polarity = <1>;
Tx Reverse, Rx Reverse:
		airoha,polarity = <2>;
Tx Normal, Rx Reverse:
		airoha,polarity = <3>;

Surge protection setting could be configured in dts. Please refer to the
following description.
Surge protection - 0R
		airoha,surge = <0>;
Surge protection - 5R
		airoha,surge = <1>;

=====================================================================
In addition, if EN8811H connects with a RESET GPIO, please check the
GPIO number, and then add reset-gpio related definition to above phy
node.
=====================================================================
reset-gpios = <&gpio 6 1>;
reset-assert-us = <10000>;
reset-deassert-us = <10000>;
=====================================================================

If without this patch, kernel cannot load up-to-date PHY driver
for the Airoha EN8811H.
