[PATCH] arm64: dts: imx8mm-nitrogen-r2: Fix I2C mux subnode name

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

Per i2c-mux-pca954x.yaml, the I2C subnodes should follow the
'i2c@' format.

Change it to fix the following schema warning:

imx8mm-nitrogen-r2.dtb: i2c-mux at 70: Unevaluated properties are not allowed ('i2c3 at 0' was unexpected)
	from schema $id: http://devicetree.org/schemas/i2c/i2c-mux-pca954x.yaml#
