its: r4: add 2g5 config (not working yet)

looks like current firmware is not compatible with old driver

phy-fw-node in mt7988a.dtsi differs

old one:
		phyfw: phy-firmware@f000000 {
			compatible = "mediatek,2p5gphy-fw";
			reg = <0 0x0f000000 0 0x8000>,
			      <0 0x0f100000 0 0x20000>,
			      <0 0x0f0f0000 0 0x200>;
		};

new one:
		phyfw: phy-firmware@f000000 {
			compatible = "mediatek,2p5gphy-fw";
			reg = <0 0x0f100000 0 0x20000>,
			      <0 0x0f0f0018 0 0x20>;
		};
