Revert "arm64: dts: imx8mm-kontron: Add support for reading SD_VSEL signal"

This reverts commit 8472751c4d.

The board uses SDHC VSELECT to automatically switch between 1.8v and
3.3v. It does not use GPIO to control the PMIC SD_VSEL signal.
The original commit intends to read back SD_VSEL value from GPIO,
but it is wrong. When MUX is configured as SDHC VSELECT, it is
impossible to read back the value from GPIO controller. Setting SION
could only enable the input path for the mux function. It could not
redirect the input to GPIO.

And value "0x40000d0" is wrong, SION is BIT30, not BIT26.
