sd_card & imx53: fix initialization problem on QSB 

On i.MX53 QSB, a "Send Op Cond" command during the driver initialization
returns another response value than on the USB Armory. As the check for
this response seems to have no relevance for the driver functionality (Linux
reads the value from MMIO but I can't find a place in the source code where
it is used), we simply remove it.

Ref #1497
