[PATCH v2] arm64: dts: imx8mq-kontron-pitx-imx8m: remove vqmmc-supply node

The sw4 output (V_1V8_S0 voltage) from the PMIC is the main supply for
the 1V8 power domain. It is not only used as supply for the eMMC.
So this voltage can not be changed and is not allowed to switched off.
Therefore we do not want to provide this regulator to the SDHC driver to
control this voltage.
