arm64: dts: imx8mp: Add pinctrl config definitions 



Currently to configure each IOMUXC_SW_PAD_CTL_PAD the raw value of this
register is written in the dts, these values are not obvious. Add defines
which describe the fields of this register which can be or-ed together to
produce readable settings.
