Some vendors, *I'm looking at you Samsung*, report support for 1.8 voltage, even though the card does not support it.
So, disable low voltage support for now until the behavior is changed to act more like what Linux does. (re-initializing the SD card and disables the low voltage switch).
Fix the switch to high speed mode for high voltages also.
Additionally, correct the IF COND reply. 0xAA is the important part.
