Changing the card voltage on the p200 is not instantaneous, especially
when switching from 3.3v to 1.8v.
I take at least 70ms for the regulator to go from 3.3v to 1.8v. Add
margin to that to make sure we don't upset the sdcard during the voltage
switch
Fixes: ef8d2ffedf18 ("ARM64: dts: meson-gxbb: add MMC support")
