This reverts commit 02f3029f18.
This patch add 3 times retry to CMD8 because the Marvell mmc controller
doesn't obey the power ramp up process in the SD specification 6.4.1.
(Please refer to figure 6.1 and 6.2 in the specification.)
The CMD0 should be send after power ramp up has been finished.
However, the Marvell mmc contorller must do power ramp up after the
first CMD0 command has been send.
This patch also affect existing platforms like Nokia N900 and other
platforms.
