Is below commit better?

ARM: dts: imx8mp-sm2s-imx8mp: Drop SD power-supply override

The SMARC evaluation carrier provides an SD card power switch that complies
with the OSM standard definition. The OSM base device tree already
describes this correctly.

Stop overriding the SD power-supply in the board device tree and rely on
the definition from the OSM base DTS instead to fix the power-supply
configuration for the SD card.
