From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>
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.
Fixes: 6a57f224f734 ("arm64: dts: freescale: add initial support for verdin imx8m mini")
