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

The sw4 output (V_1V8_S0 voltage) from the PMIC is also used as supply
for the eMMC. This voltage can not be changed and is not allowed to
switched off. So we do not want to provide this regulator to the SDHC
driver to control this voltage.
