[PATCH] ARM: dts: imx23/28: Remove unneeded "fsl,mxs-gpio"

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

According to gpio-mxs.yaml, only "fsl,imx23-gpio" or "fsl,imx28-gpio"
are valid compatible strings.

This fixes the following dt-schema warnings:

imx23-evk.dtb: pinctrl at 80018000: gpio at 0:compatible: ['fsl,imx23-gpio', 'fsl,mxs-gpio'] is too long
	from schema $id: http://devicetree.org/schemas/gpio/gpio-mxs.yaml#
