When switching card voltage to UHS voltage the mmc framework tries to check the card busy signal, meaning the card pulling DAT0 line low, before the switch is made. Drivers that does not implement the card_busy function will manage to do the switch anyway, but the framework will print a warning about not being able to verify the voltage signal.
Implement card_busy function.
