arm64: dts: imx8mp-kontron: Add support for reading SD_VSEL signal

This fixes the LDO5 regulator handling of the pca9450 driver by
taking the status of the SD_VSEL into account to determine which
configuration register is used for the voltage setting.

By making sure, that we always use the correct register
when controlling the regulator we can fix an
actual bug where the wrong IO voltage is used.
