Subject: [PATCH 1/2] arm64: dts: imx8qm-mek: mux and hook up GPIOs related to SD1

Add pinctrl node grouping USDHC1_DATA6, USDHC1_DATA7 and USDHC1_RESET_B and use
them as Write Protect and Card Detect for usdhc2 and regulator enable for
SD1_SPWR respectively.

Fixes: 307fd14d4b14 ("arm64: dts: imx: add imx8qm mek support")
