[U-Boot] AT91 working SD with u-boot

[Sebastian Heutling]

Hi Konrad,

are you using the AT91SAM9G20-EK?

In that case the difference between us is that I'm working on a 
different board which is using the slotb MCI while the AT91SAM9G20-EK 
uses slota.

In case of slota it just worked because MCI_SDCR is 0 on reset but for 
slotb the SDCSEL field must be set to 1.

Regards

Sebastian Heutling
