ARM64: dts: verdin-imx8mm: Add off-on-delay to usdhc2
The hardware of verdin has some bypass caps after the switch that switches power to the sd-card. These caps are resulting in a slow discharge. Add off-on-delay to set a minimum off-time of the regulator so it can fully discharge until it turns on again. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
