Atmel SD/MMC info error (report only)

[gpontis at spamcop.net]

If CONFIG_MCI_ATMEL=y and CONFIG_MCI_INFO=y, some useful info about  
the SD/MMC card can be displayed with "devinfo atmel_mci0". However,  
the parameter showing the number of bits used for transfers is  
incorrect. A SD card supporting 4 bit transfers is reported as using 2  
bits. A logic analyzer shows that in fact all 4 bits are actually  
being used.
