Michał Żygowski 654a45d2ad src/sb/amd/pi/hudson/sd.c: disable SDR50 tuning and set correct clock freq in SD2.0 mode
According to BKDG for AMD Family 16h Models 30h-3Fh Processors
SDR50 tuning should be disabled in 0xA8 register.

Also fix clock frequency setting in 0xA4 for stepping >= A1
which caused reduced performance of SD cards transfer speed
even by half.
