Subject: [PATCH 1/1] arm64: dts: imx8mp-skov: add pinctrl-name 'reset' to fix CHECK_DTB warning

Add pinctrl-name 'reset' to fix below CHECK_DTB warnings:
  arch/arm64/boot/dts/freescale/imx8mp-skov-basic.dtb: switch@5f (microchip,ksz9893): pinctrl-names: ['default'] is too short
	from schema $id: http://devicetree.org/schemas/net/dsa/microchip,ksz.yaml#

The commit (e469b87e0fb0d dt-bindings: net: dsa: microchip: Add strap
description to set SPI mode" force use two pinctrl-name 'default' and
'reset'. switch@5f doesn't use SPI, so it is safe to use the same pinctrl
setting for both.
