Low capacity 2GByte cards are set back to block size 512, so block_number
should be doubled.

The SPI SD card driver sets the block size of low-capacity 2GB cards to 512
bytes even though the card reports 1024 bytes.  However, the number of blocks
should then also be doubled.

Failing that, the disk device layer (rtems_disk_create_log()) barfs because the
partition size is larger than the disk size.
