arm64: dts: freescale: imx8mm-verdin: Fix SD regulator startup delay

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2101915

commit 0ca7699c376743b633b6419a42888dba386d5351 upstream.

The power switch used to power the SD card interface might have
more than 2ms turn-on time, increase the startup delay to 20ms to
prevent failures.
