MLK-16287 imx8qxp_arm2: increase the off-on-delay for usdhc2 vmmc supply

Current value of "off-on-delay-us" is 3500us for usdhc2 vmmc regulator,
this is measured value but not have margin added. We found QXP ARM2
RevA1 board can't work with this value. So increase it to 5000us with
1500us margin added.
