RM-7588: imxrt1170: pinctrl: dts: Fixed a typo in the compatible string

[asanochkin-emcraft]

Due to a typo in the compatible string for the iomuxc_snvs group pins, the pin names are shown incorrectly in the debugfs:

/ # cat /sys/kernel/debug/pinctrl/40c94000.iomuxc_snvs/pinmux-pins
Pinmux settings per pin
Format: pin (name): mux_owner gpio_owner hog?
pin 0 (IMXRT1170_PAD_GPIO_LPSR_00): gpio-keys 40ca0000.gpio:384 function iomuxc_snvs group keysgrp

With this patch applied the iomuxc_snvs group pins showed as follows:
