Added them initially, but later dropped because of some logs like
"pinctrl@xxxxxxx: usdhc1grp:fsl,pins:0: [...] is too long" shown by
"make dt_binding_check dtbs_check DT_SCHEMA_FILES=[...]/fsl,scu-pinctrl.yaml"

Same logs are shown for "fsl,imx8mq-pinctrl.yaml". Will add the items description in the next
version.

Thank you,
