Ulf Hansson b33d46c398 mmc: core: reset card voltage after power off
At power off, reset OCR mask to be the highest possible voltage
supported for the current mmc host.

This solves the re-initialization during the power up sequence.
The voltage may have been decreased due to the card accepts a lower
voltage than the voltage used during the initialization sequence.
We need to reset the voltage to by the host highest possible value
since according to specification the initialization must always be
done at high voltage.
