ARM: dts: imx6ull-seeed-npi: fix fsl,pins property in tscgrp pinctrl
The property is "fsl,pins", not "fsl,pin". Wrong property means the pin
configuration was not applied. Fixes dtbs_check warnings:
imx6ull-seeed-npi-dev-board-emmc.dtb: pinctrl@
20e0000: uart1grp: 'fsl,pins' is a required property
imx6ull-seeed-npi-dev-board-emmc.dtb: pinctrl@
20e0000: uart1grp: 'fsl,pin' does not match any of the regexes: 'pinctrl-[0-9]+'
