arm64: dts: imx8dxl-ss-conn: Fix Ethernet interrupt-names order

Per snps,dwmac.yaml, the interrupt-names entries should be in the
following order: "macirq", "eth_wake_irq";

Change it to fix the following schema warnings.

imx8dxl-evk.dtb: ethernet@5b050000: interrupt-names:0: 'macirq' was expected
	from schema $id: http://devicetree.org/schemas/net/snps,dwmac.yaml#
imx8dxl-evk.dtb: ethernet@5b050000: interrupt-names:1: 'macirq' is not one of ['eth_wake_irq', 'eth_lpi']
	from schema $id: http://devicetree.org/schemas/net/snps,dwmac.yaml#
