arm64: dts: imx8mm-evk: increase delay for SD VCC regulator
The commit is based on u-boot commit 247bbeb74c ("ARM: dts: imx8m:
increase off-on delay on the SD Vcc regulator"). Add a delay of 20ms to
ensure that the board capacitances are discharged and to ensure that the
SD card power-cycle specification is guaranteed.
