arm64: dts: imx8-apalis-v1.1: Remove reset-names from ethernet-phy

The 'reset-names' property is not a valid one under ethernet-phy
and causes the following dt-schema warning:

/imx8qm-apalis-v1.1-eval-v1.2.dtb: ethernet-phy@7: 'resets' is a dependency of 'reset-names'
	from schema $id: http://devicetree.org/schemas/reset/reset.yaml#

Remove this property.
